That has more to do with them being lousy shots than respect for life. Or hadn't you heard about the rioters shooting at police and firefighters?
Four random shots.
After 8 days of riots.
Those shots could have killed somebody, but clearly there's not a mass, armed movement going on here.
France is now experiencing what America experienced with the blacks in the 1960s. The American approach was to give the blacks political control of major cities, allowing them to have their own sources of patronage, affirmative action, and expanding the American government to provide them with jobs. This was decided to have been the better course than a civil war.
And in France it will be the same way.
The obvious solution is to bring down the barriers of exclusion. This is a warning shot. Like the Americans, the French will heed it.
