However I think that we really need refine when warrantless searches can occur. Right now many searches seem to be done with very little evidence to justify them. I think this protection should apply to your mind and phone just like it applies to your house. This probably also needs to be considered at border crossings. Right now they have basically unlimited rights for searching what you have on you with little to no evidence.

to be fair to the current justice system, a lot of times you can just hit the courts with "excuse me sir, this was unwarranted" and assuming it was actually unwarranted, they should overthrow it immediately.
