Firefighters lured into a trap...?

Here is what happend ( based on Detroit ) A man lit the fire and the FF came to put it out, He didnt want it put out or he would not have started it. So he started to shoot. The only reason this is a big deal is after sandy hook and that retarded shooter . Medics get shot daily in Detroit thats why there is a 20 min delay.

Who can predict the evil that resides inside a man's heart.

Was his ultimate motive to destroy the stability of the systems that maintain society?

or was it a childlike rage that wanted to destroy things he hated and watch it go up in flames.

If it was the latter, then he did not want the firefighters to put out the fire.

If it was the former, then it is yes to your question.

I'm not sure if they were lured, or if the shooter wanted them to stay away because there was something the house the house owner wanted burnt beyond recognition.

Perhaps the house-owner was shooting at the firefighters to scare them away from the house, because there was something in the house he wanted destroyed.

We shall see as the investigations unfold.

The idiot who did that had already served time for killing his grandmother with a hammer. Should we ban hammers, too?
