U should not have consented to the search or got out of the car speeding is not grounds to search the car. When the cops said get out iam searching the car u say NO politly but clearly and repetavly and in 2 cases with me i used this method they stopped their ranting and went on their way and so did i.Know your rights it's okay to tell cops NO go to some stoner sites and look up how to handle a traffic stop AND IF THEY PERSIST PEACFULLY RESSIST ARREST and just simply lay down and don't respond to them. I have never had to do that but i can make it real hard on them i weigh 350 and know my rights that's very bad for the police and good for me and it will work for everyone else as well lol.
I have to say that many "minority" comedians have very funny routines involving this same "phenomenom," Honestly guys, stop "trying" to be hard/crazy and try to co-operate with them until they let you go. I am by no means a thug but people with any street/common sense knowledge at all should be aware of what can happen, just don't give those crooked bastards anymore reason to do you any harm. ( I am aware that there may be decent cops out there)
