LOl, It's been so long since I commented on this board, but I couldn't resist this one....
But firts, why would u ask these questions? Are you interested in performing such acts? If yes, then why? Why would you do hardship to the people who protect you from harm everyday?..........Ok, now to your answers, I have encountered your questions NUMEROUS times, your first, is a good one. People do that all the time, I have initiated pursuits such as these more than once, and not ONCE have they gotten away, simply because it takes me 2 seconds to get on the radio and get someone to the next street corner where the "bad guy" is driving to, plus those new chargers are bad ass fast!
Second....You say as a "joke?" Explain the expressions you would make that indicates your are joking? and how would anyone know that?....This one is more about common sence and situational awarenes...If im walking thru a drug park where two guys just made some strange hand movements, yes I could justify and elaborate a suspicious circumstance. I have tho encountered stupid hippy skater kids who pull that "joke" on me, I simply look away and thank god for stupid people, less competition for me in life and my future kids....
Third, is my favorite one, especially with rich kids during a party....There is something called a "fresh pursuit" AND "exigent circumstances" that allow a officer to use his discretion that enter wihtout a warrant. I Love this one becasue the as we call them "back street lawyers" are always so confused when the door gets kicked open and they hit the ground with 200 pounds on top of their back. If a "bad guy" is running away form me and into a house (happens all the time) infact it happened to me 8 days ago, then this would fall into a "fresh pursuit" policy and the door comes down and he get's taken down...Even more is that if you slam the door into a cops face during ANY criminal investigation (like lets say a stupid loud party call where rich kids think they dont have to play by the rules and slam the door shut during my investigation) Police can (and I have this summer) kick the door open and arrest the person for intefeering with a police investigation and ofcrouse continue the investigation.....I kicked in a door for that exact same reaosn this summer and the dumb kid was leaning right against it trying to show off that he knows his right, he ended up with a bloody nose from the door being kicked in, and then I explained him MY RIGHTS, often people don't realise that cops havee rights too, which are quite extensice, simply because not one situation is the same, so common sence (which half the populations of SHEEP, another term military and law enforcement uses for people) DO NOT HAVE...
Im sorry to ramble on so much but at least you will be one more educated person to know that police are here to help and protect you, all the good cop movies make for good entertainment but do not show the real side of police work...
