Social media bans for kids are a huge trend--yet bad policy and likely unconstitutional. These laws don't just affect minors. They force adults into cumbersome age verification. I broke down the legal and social fallout in my new piece for @TheHill thehill.com/opinion/tec...

Frustrating that in an era where 80 % of major law enforcement agencies have body-worn cameras, ICE has so few of them. President Biden signed an Executive Order requiring body-worn cameras---which President Trump repealed on his first day in office.

Laird v Tatum was a terrible decision that continues to haunt our democracy half a century later.
ICE agent asked why he's taking pictures of a legal observer's car, replies: "Cuz we have a nice little database and now you're considered a domestic terrorist. So have fun with that."

Exactly this--having to deploy the police to protect the National Guard reduces police resources for combatting crime, the supposed rationale for the Guard present in the first place.
The National Guard troops were going to free up DC police to have more capacity to fight crime, but now the police are going to patrol with the Guard to protect them? Maybe just remove the Guard - we are wasting resources and putting troops at risk for show.

Agree that this use of AI in policing is probably premature, but I like that officers are thinking about how to use AI to increase officer compliance with policies. We should be supportive of that instinct.
