Will UK allow authorities to kidnap and murder?

The “Covert Human Intelligence Sources Bill” is rushed through UK parliament. It may allow undercover agents from 13 different law enforcement and government agencies to break the criminal law. Kenny MacAskill is one of many who think it goes too far:

The powers being authorised legitimise actions by police and the security services that are simply unacceptable in a democracy. Allowing the most serious criminality, including potentially kidnap and murder, not only threatens our society but can corrode those institutions from within.
