Let me just say this about that. Too bad. The guy should have gone while he had the chance.
Every law enforcement officer has to deal with these idiots from time to time. It's fairly easy. You ask them once, you warn them once, then you say the magic words; You're under arrest.
Louisiana law allows me to use whatever force is necessary to effect an arrest and a goodly portion of the police academy is spent talking about Use of Force. It's fairly simple:
A person shall submit peaceably to a lawful arrest. The person making a lawful arrest may use reasonable force to effect the arrest and detention, and also to overcome any resistance or threatened resistance of the person being arrested or detained.That's it. I can use reasonable force to overcome resistance. I get to decide what is reasonable, based on my training and experience. I have lots of training and over 25 years experience.
If I ask you to leave and you don't, you probably aren't going to like what comes next. I have spent most of my adult life dealing with idiots, meaning folks who can't take a gentle hint to depart. While I won't go into the particulars of technique, it involves joint locks, strong empty hand techniques, OC spray, the baton, and handcuffs. When it's over you still leave, except in the back of a cruiser and then you have to make the phone call for bail.
Save yourself the trouble of making bail. When an officer asks you to leave, say YESSIR and depart.
