I'd like to point out that when it comes to the 4th amendment, the protections afforded to your home where you reside are much stronger than the protections afforded to an external storage unit or a vehicle that you don't live in. I'm not really up to date on this but there is a good chance that the cops searching TacoMac's tennant's storage locker discussed previously was totally legit even without the tenants permission.
Of course, the discovery of enough explosives to take out a city block would require calling the bomb disposal unit at a minimum and probably cordoning off the block at risk. That would be big news and we'd probably be able to find articles about it online. If only
@TacoMac hadn't taken his ball and gone home...
