you have rightly said that Police should not be having this kind of right to conduct killings. Excesses at the hands of State machinery is always questionable and need probe.But Political parties` overtones for a community or the other,reflects- political maturity is deteriorating. True stories behind such incidents may be still painful.All men in power tend to misuse.System is weak.People understand mechanisms of allegations and counters and games politicians play,and people as always fall prey.
