Why do you need to arrest someone just to warn them?
One case I read of a guy who got in trouble for a social media post, he was called into the station and they basically forced him to sign a paper otherwise he couldn't leave as they'd just keep interrogating him, where I'd imagine they threatened to get the courts involved unless he admitted he was wrong for doing it. Which is why most of them don't end up as convictions.
It's basically a very aggressive warning.

> Mr Foulkes was detained in a police cell for eight hours and questioned in relation to a potential charge of malicious communications. He said he ended up accepting an unconditional caution because he feared the investigation could affect his visits to his daughter in Australia.

> After being questioned for several hours, North was released without charge.
So pretty much half the time than in the US. (County of Riverside v. McLaughlin)
-In the United States, police generally cannot hold you for more than 48 hours without formal charges or a probable cause hearing before a judge.
My main concern is the fact they are raiding peoples houses, taking electronics, and aggressively interrogating people for hours over a tweet, then pushing them to sign a document admitting they did something wrong without charging them. While everyone pretends they just got a 'warning' and it's not a big deal that this happens to thousands of people a year.
