This is not new, it's been like this for decades. You start mouthing off to a cop and they can arrest you.
Nonsense. For example, giving a cop the finger is fully protected speech (as it should be) and not only can you not be arrested for that – it doesn't even give rise to reasonable and articulable suspicion to allow the cop to stop and/or detain you.
The first amendment or the right to free speech means the ability to speak against the government without fear of being arrested.
Even if your learned discourse on the First Amendment was right (sidenote:
it is not) is a police officer not an instrument – and a rather blunt one at that – of the government? Wouldn't that mean the First Amendment protects you when you say things to the officer, who is acting under color of law and represents the authority of the state, since you are, therefore, directly criticizing the government?
Come on Professor. Share your legal wisdom with us...
Nothing to do with mouthing off, threatning people or saying hateful things. Sometimes people just need to SHUT THE FUCK UP.
Oh, boo hoo. We can't say hurtful things.
Have you ever read any of the seminal First Amendment jurisprudence cases? Or, hell, the First Amendment itself?
My guess is no. Or if you have, clearly you didn't quite understand.
I also find it amusing and oh so slightly ironic that in saying that one can't say hurtful things and can't mouth off, you end up resorting to mouthing off.
