If someone started firing on rescue vehicles, they do need to be stopped. I agree.
What bothers me is that people are looking at it from a very different situation - one in which you are sitting comfortable in your office, typing on a computer because you have electricity, in no danger, have a place to live, food to eat, and a bed to sleep in, wondering why chaos has broken out to people that have none of that.
I don't excuse someone shooting at a rescue vehicle.
But people in panic mode do things they never thought that they would.
As I used in an example:
http://www.theage.com.au/news/iraq/hundreds-killed-in-baghdad-stampede/2005/09/01/1125302656200.html
"Most of the victims were women and children who drowned or were trampled."
These people were going to Mecca. Were you to ask someone who stepped on a child in panic if he would ever do such a thing, he would swear he wouldn't.
Even Peter, when he feared for his life, denied that he knew Jesus.
Panic and fear makes people do that opposite of what they think they would.
I simply wish that we would stop focussing on the few incidents of people who did something really stupid, like shoot at a rescue vehicle, and instead, focus on what we can do to help the victims.
