All it takes is a leader to do it once and the others will follow especially if that leader is a Iraq vet and displays some knowledge of tactics.
But it would not suprise me a bit if these were muslims who have just been waiting for this day.

From the above link:
"But by last year (2004), the number in New Orleans had crept back up to 265. There had been 192 this year by mid-August, compared with 169 at the same time in 2004. Adjusted for the city’s size, those numbers dwarf murder rates in Washington, Detroit, Baltimore, Atlanta, Chicago, Los Angeles and New York City."
"The city now has 3.14 officers per 1,000 residents — less than half the ratio in Washington, D.C."
"NEW ORLEANS - Last year, university researchers conducted an experiment in which police fired 700 blank rounds in a New Orleans neighborhood in a single afternoon. No one called to report the gunfire."
So, has the crime rate gone up since the flood? I'm no longer so sure.
