In regards to the bomb idea, I like it. However, you seem to have put little/no effort into what a BDS is. Of course, many people don't know what exactly a BDS is either.
A BDS (Bomb Disposal Squad) works from either one of three entities: Military (although often strictly for military uses), Police (often called a 'bomb squad) or a fire department with specialized services. For example here. In the city I live, the police and fire department are jointed in this task. If a bomb was ever thought to be planted, the fire department would send Hazmat 1 and Squad 20 (as well as the nearest available 3 engine companies, 2 ladder companies, a rescue, and 3 ambulances + MCI 1) and the police would send the SWAT unit, HRTT 1, and the sheriff would dispatch its anti-terror unit. That's quite alot, but given the situation, it's better to over react and waste resources than to send a single fatass in a pick up to look at it go 'ehh, I'll kick it and see what happens'.
I did propose a fire/rescue service a while back (
viewtopic.php?f=620&t=102289 ) and this would be a good task for them. In addition, the LSPD could also be given the task, but the issue there is the LSPD currently is filled with cafe users who aren't bright enough to fucking understand that shooting a civilian who isn't wanted is a good way to get quized/jailed. For something this complex, time sensitive, and so one, you'd want a team with dedicated people who know how to actually accomplish something outside cuff abuse.
Still, if the staff are willing to put in the work, I'd support the idea.
As for breaking into cars, sure why not. Seems like a good way to annoy the cops.
