They where probably freaking out on the future consecuencies of this shootout. this is trouble for everyone.

alien jesus could you explain this a bit more? i find it interesting but cant quite understand it (english is not my first language)

I´m pretty sure that the explosion WAS NOT caused by our heroes bullets. That explosion was triggered by the villains themselves to delete all evidence of whatever was going on in there (most possibly a drug lab, like Velcoro notices)
