Can anyone explain how this process works? I read somewhere on here about screeners go through your bags and leave a note that they did so. Is that only when you use the special locks that they can open? What do they do if you don't have that type of lock? Do they just break your locks? Or do they wait and have you open the lock for them and do a baggage check like when we go through customs after international flights? I'm really not sure I like the idea of anyone going through my bags without me there. Not that I don't trust them but okay, I guess I don't. Do they do this often and with all bags? Is it better to have the TSA locks or not????
