Burn Notice Season 4 Episode 17

Michael: Everything okay, Fi?
Fiona: We used to talk about where we were going, what we wanted our lives to be. And now the only time we talk about our future is when someone's coming to end it.

Brennen: A good general knows his army is only as effective as its weakest soldier. And a great general has no weak soldiers in his army.

Michael: (voice-over) When a real-estate bubble bursts, it's tough on the civilian population. But it's a field day for spies. Empty buildings provide excellent cover for scouting in an urban environment. And it's always nice to plan and execute illicit operations in air-conditioned comfort. Unfortunately, all that unoccupied space is a playground for criminals, too.

Michael: (voice-over) If you're looking to frame a specific group for a bombing, you use their design plans, their construction materials, and their particular brand of C-4. Bomb experts know that not all C-4 is the same. The same taggant chemicals that allow manufacturers to identify their own product will also allow forensic teams to track down the source country to determine who's to blame just like checking the label on a t-shirt to determine where it's made, only a little more complicated.

Sam: Okay, so you want us to just waltz into some FBI building and politely ask them to use one of their computers?
Brennen: I'm gonna go out on a limb here, Sam, and guess you're not the brains behind this operation. Computers that can access the federal database also live in federal courthouses. Did I go too fast? Are you lost, Sam?
Sam: Don't take my silence for confusion, Brennen. I was just trying to kill you with my mind.
