granjura The southern states of the USA – the ones LBJ reckoned the Democrats had lost for decades once he signed the paper – aren't slave states any more. Of course, there are still rednecks but, generally, it's been long time since trees bore "strange fruit". Sadly, some people will always hate irrationally those who are easily identified as being different, whether black, brown, Jewish, Moslem, whatever. So crimes of this sort may well be racist but are also gun crimes, in that guns are used and readily available.
America really does need to learn that it isn't a cowboy movie any more.
