When a politician violates the constitution, why aren't they criminally prosecuted?
There are plenty of examples out there where a politician passes a law that they most likely know wont stand up in court. Someone has to prove standing and incur the cost of trials, appeals, etc. to get the law overturned.
Sometimes they knowingly do this for "temporary measures" because they know it will take longer to go through the courts than they need to to be in effect. Abuses in "States of Emergencies" come to mind as a common one, but the current example with the governor or NM banning the carrying of guns is a recent example.
Why are there no criminal consequences when these things are done? They have deprived the populous of their constitutional protections, which by default would be civil rights violations that if any of us were to commit, we'd be locked-up.
Without any criminal culpability, there's no reason for them not to do it again. There's also no example being set so that other politicians don't do the same thing in their jurisdictions.
