RealClearWorldAttackers in Orlando, Brussels, San Bernardino, Paris, and Boston share a stark commonality with each other and with other terrorists: They already had come to the attention of law enforcement or intelligence agencies before they killed. In each instance, authorities decided that despite radical leanings and prior offenses the suspects would not commit acts of mass violence, and so discontinued investigations or did not share information across jurisdictions.
