hahaha warrant... thats funny as hell man. why would they need a warrant?
you must have forgotten that if a cop SEES you breaking the law, or has PROBABLE CAUSE to believe that you have broken the law, he doesnt need dick to search you.
if a cop pulls you over and the car reeks like weed, he doesnt need a warrant to search. if he sees a bag of drugs sitting on the floor, he doesnt need a warrant. if he comes to my door and sees a dead body lying in the floor, he doesnt need a warrant to enter.
honestly though, they probably wont even look at your phone. they will just write you a ticket.
its just like running a stop sign. you say you didnt, cop says you did. take it to court, who do you think the judge will believe?
