The way things are going, even if LEO found dangerous chemicals [red mercury!] etc inside the U-Hauls, they would let the folks go anyhow as has already happened in Canada...and here with the "israelis."
Anyway, a private [non-commercial] trailer can not be searched without a warrant, even if the driver is arrested. A very private way to go, eh? And the jihadis know this I'm sure....
Exactly my point. Criss-crissing the USA could be all sorts of goodies meant to bring down our country. I'm sure I'm a minority because of "privacy issues" in our country, but I'd sure rather see random checks on U-Hauls than nuclear bomb damage reports because it wasn't done. This is, after all, a time of war and the enemy is within.
