Even as I type this, over the last week, Palestinian security forces (mostly presidential guards and the counter-terrorism units) have been raiding houses in the city and refugee camps --- and clashing with gunmen and rioting youths, as the Palestinian Authority (PA) tries to establish security in a increasingly restless and volatile populace, in a crackdown on drugs and weapons. Whatever you may think of clashes between the Israeli and the Palestinian, the clashes between their own are much worse. And the PA Security Forces are not so concerned about the civil rights and liberties as you would think they are given the tears and complaints about the Israelis. But make no mistake, a bigger band of thugs with guns you'll not find than the Palestinian Presidential Guard.
