This is an excellent example of letting the police handle crime.
It probably doesn't fit with the take-the-law-into-their-own-hands attitude of many of our more vehement pro-gunners, but it was the right thing to do, the right way to handle things. It must have been very difficult for this firerighter to not only focus on the emergency job at hand, but not to give away what he was thinking so that the police would have a better chance of apprehending the suspected perpetrator without any advance warning to him.
This man personifies the support of due process, law enforcement and the legal system, but also he represents the kind of compassion that returns good for evil in his response that is essential in civilized society.
I hope all of this fire fighter's things are returned to him very quickly, and that the criminals are properly held accountable by the courts.
