Comment Yeah? You can be personally searched too (Score 1) 390
You can be stopped and searched anywhere within x number (I forget how many) miles of any US border.
Just try to not get stopped while traveling down near Mexico. There are road blocks, checkpoints, etc. where they can and will search your stuff, question you, etc. All without any suspicion of anything. Search Youtube for videos of confrontation between US citizens and the police in these areas.
I don't see why electronic equipment would be any different.
