@DennisBellDCAFC @LordOrk 2. Really expensive projects like this get built less often outside London because there aren’t enough potential passengers to justify the cost. More journeys start/end at South Ken tube each year than at Manchester Piccadilly, Leeds or Edinburgh Waverley.

@DennisBellDCAFC @LordOrk There are a few reasons why transport upgrades in London are expensive. Two important ones: 1. Building in London is often logistically hard. The site at South Ken, for example, is extremely constrained by surrounding roads and buildings. …

Inside the £120,000,000 upgrade to South Kensington Tube station A new accessible station entrance will be opened on Thurloe Street, with step-free access to the ticket hall, platforms and the museum subway. New station will be unveiled sometime in 2029 apple.news/Ao5fqWdECSiqPU…

@DennisBellDCAFC @LordOrk It’s largely being funded by building new flats next to the station, and the rest of the money is coming from TfL (ie Tube fares/London taxpayers), so it couldn’t have delivered anything elsewhere in the country.

@LordOrk £120m for a station upgrade. What could this have delivered around the country?

@grahamwettone @zarahsultana “Thanks, I wasn’t aware of that” would have been a perfectly reasonable and polite response. I appreciate social media makes people defensive, but sometimes there’s really no need.

For more than 25 years, the Metropolitan Police has been repeatedly found by independent investigations to be institutionally racist, misogynistic and homophobic. The brass neck is staggering. As Commissioner, Mark Rowley’s job is to serve the public, not to make political attacks. Shame on him.
Metropolitan Police@metpoliceuk

“Apprehending violent and dangerous criminals is a full contact and messy task which may appear shocking to observers with little experience of policing in the real world.” Commissioner Sir Mark Rowley writes to Zack Polanski.

One of my reflections on the Golders Green arrest is that I suspect there would have been less controversy if the suspect had been confronted and shot dead by armed officers, if he had similarly refused to put down his knife and continued to advance towards officers.

@whippletom Partly because at the start they don’t have the necessary information (ie how much money they’ll have left on day X) that they need to decide whether to stop to work at any particular point in the race.

My beef with race across the world: if you think at any point you are going to have to take a job, why not do it in the starting place, which is a high wage economy, rather than waiting until you are in Burkina Faso?

@JonathanWiltsh7 @ZoeJardiniere I agree it’s perfectly reasonable for people to expect an explanation when police use force like this. I’ve tried to explain the basic legal position here:
Matt Ashby@LessCrime

@nickyjanehill In rare circumstances, yes. Officers are taught during training that any strike to the head could potentially cause serious injury or death and so may only be used when necessary and proportionate. In this case, I would say it is both. …

Completely agree. I don't know where the line is in terms of use of force depending on the various factors involved here, but would seriously like an answer as to where that line stands in the law, and in this situation, whether that line crossed or not. People have a right to ask for that clarification without being lambasted.

@grahamwettone @zarahsultana No, but you said he wasn’t an elected politician and that isn’t quite true. Devolution means it’s been a long time since MPs were our only full-time politicians!

@zarahsultana This isn't political - Mr Polanski isn't an elected politician. He commented on an operational policing issue & completely within the remit of the Met commissioner to respond to that.

@sc_wadsy @nickyjanehill @UnlikelyLadone It definitely looks like the Taser was working when the subject fell over, but that doesn’t mean it was still working when he was on the floor and not releasing the knife. As I said in a previous reply, it looks like it wasn’t working at the point where the officer kicks him.

@sc_wadsy @nickyjanehill One of the limitations of Taser is it only works if everything goes right. For example it often fails because the subject was wearing thick clothing, or it was fired at the wrong distance, or something gets in the way of the circuit.

@sc_wadsy @nickyjanehill That’s a good question, and I did some checking for before posting. On the body-worn video released by the Met you can clearly hear the Taser discharging. But you can also see that it’s very unlikely it was having an effect because the wires are wrapped around at least 3 people.

@brobinson952 @nickyjanehill A baton only works at very short range (not good when someone is trying to stab people), and only works if the officer has enough space to swing it (not good when there are other people close by). That’s why officers rarely use batons outside riots.

@DYamamma @nickyjanehill An officer might believe the only way to stop someone fleeing after being stopped for littering is to Taser them, but it's very unlikely that force would be considered proportionate because Taser is a high-level use of force and littering isn't that important.

@DYamamma @nickyjanehill No, the law requires force be both necessary and proportionate. It's not legal to use force that is necessary to achieve an objective if the force is grossly disproportionate to the objective. For example …

@brobinson952 @nickyjanehill Pepper spray wouldn't necessarily make someone drop a knife, although it would disorient them. But it might also disorient the other officer who is grappling with the suspect, which would make the situation worse. Pepper spray would not be a good tactical option here.

None of these elaborate AI detection methods are suited to very large classes in public higher ed. Instead of refining detection techniques, unfortunately you just have to change the assessment method instead . You’re not going to win the detection battle (and mentally survive)
Robert Pondiscio@rpondiscio

A modest proposal to the solve problem of AI-generated student essays: give each student a surprise quiz based on their own papers, administered in class, without their submitted work to refer to. Use AI to generate the customized quizzes. Fair is fair.

@eoinmauricedaly @CianOConcubhair I see colleagues elsewhere complaining at length at having to read AI-generated essays, but that always makes me wonder why they don’t redesign their assessment to design out the problem. It’s almost always possible.

@eoinmauricedaly @CianOConcubhair We don’t use AI detection tools at all (uni policy specifically prohibits it because they’re not very accurate), so we’ve reviewed all our assessments and made substantial changes to about half of them to either prevent AI use or facilitate it, as appropriate.
