Any act of terror that takes innocent lives must always be shocking,, and not accepted as the new normal.However I am aware that every day twenty four seven there are dedicated men and women who prevent even greater carnage. They are found in all of those departments and organizations whose sole purpose is to uncover plots against the targets of terrorists.It is horrible that any act occurs ,but I am sure that there are literally hundreds of evil doers that are stopped in their tracks by the professionals whose names we will never know.I applaud them, and hope that as time goes by they will continue to uncover future attempts here and abroad.
