Next time ask "am I free to go?" (and insist on it being answered) and if he says no, ask why. He is legally obliged to tell you, and if you phrase it like "What is your reasonable suspicion for detaining me?" you clue him in that you're not going to be easy prey. They still mostly count on intimidation and the fact that we don't know our rights, of which we still have a few left.
That, and play stupid. REALLY stupid, as in the only three phrases that should be in your vocabulary when talking to government pinheads besides "Am I free to go?" are "huh?" "What do you mean?" and "Why?" Alternating between those no matter what they say will drive them insane but not enrage them since you're clearly just dumb as a post, which is exactly how you want to seem. They are intimidated by intelligent people because they know at some level they're in over their head so they tend to overcompensate in encounters with intelligent but uncooperative citizens by using more Dumb Cop Tricks.
This is true. My natural possum reaction is to realllllly realllllly dumb it down. I've had some good run ins though too because I was really really compliant.
There was one time, I should have definitively gotten a DUI, but I was proactive. The cop walked up to my window, I handed him license and reg, and I said "good evening officer, Before you ask, yes, I have been drinking, and yes, I have probably had too much but didn't realize until I was already on my way. I will be fully compliant with whatever you need me to do."
Now, I didn't have any contraband on me, I never travel with anything illegal if I'm drinking, so I don't know how I would have reacted to that situation. The guy looked and me and I made my best scared faced and he said, "do you have any friends that you can call?"... so whew to that.
However, while we we're waiting for my friends to show up (only took like 10 minutes), he was busting my balls, made me breath alyzer, didn't show it to me, "oh, yeah, you're fucking bombed.." "They better get here fast or you're fucked buddy"...
So I find that most LEO have a need to feel better than other people, to control other people, to haold other peoples emotions and lives in their hands.. He let me go, so I'm thankful all in all...but he didn't have to make it an unpleasant experience for me since I went out of my way not to make it an unpleasant experience for him.
Mungo. That is fucking sick. I don't even know what to say to something like that, those people should be locked in a cage.
