If you are referring to the guy with the propane nozzle, I didn't know that would alert a bomb dog, did you?
If you mean anyone in SEPTA, I'm reminded of a story from WWII where a private in newly invaded France got his unit (battalion?) up all night for a gas alert. One of the war gases smells like new mown hay and they were camped near a hayfield. The private got a "well done" from his CO.
A traffic snarl is a lot better than what would happen if they missed a bomb.
I don't have any problem with SEPTA (well, on this issue, talk to me at 6:30 when I've been waiting for the 23 bus for 40 minutes and that might be different). It sounds like this guy was just trying to cause an incident. Getting on the train with the huge back pack, not responding to the conductor, stuff like that.
