ABSTRACT
Investigating terrorist attacks is much more complex and politicized process than regular police work, and far less confidence can be placed in public statements allocating the blame. In order to investigate terrorism, law enforcement agencies must use various clandestine methods, including infiltration and double-agent tactics. Successful terrorist investigations demand infiltration, either by government agents, or by turncoats or defectors within that organization. Terrorist groups practice systematic deception and false flag methods, so do law enforcement agencies. Agencies wishing to suppress terrorism must, of necessity, operate in complex and dirty clandestine world. In terrorist war, any effort that is solely defensive is bound to fail: just to protect is to lose. In the terrorist world, however, arrests can in some cases be seen as a kind of failure, especially if they are publicized. In extreme cases, police or intelligence agencies can find themselves in the position of "going native," to the point of working for and with terrorists or terrorist regimes.
