Does Monitoring Muslim Communities Stop Terrorist Attacks?

The mosque attended by the recent New York terrorist had previously been under surveillance from an NYPD program that was later cancelled. News of this has led some to wonder whether or not cancelling the program was a mistake. When evaluating counter-terrorism methods, it’s important to be objective. The metric that really matters is “Did the program work?” So, the question to be asked is: Could a cancelled Muslim community surveillance program have stopped the recent terror attack in New York?

If the success record of that program in stopping terrorists is anything to go by, that seems unlikely.
