Why did it take thousands of police officers to capture the Boston terrorist. Could it have been the gun control laws in Boston!

AS I WATCHED THE EVENTS IN BOSTON UNFOLD, I WAS AMAZED BY THE SHEER NUMBERS OF LAW ENFORCEMENT PEOPLE ON THE STREETS DURING THE MANHUNT FOR DZHOKHAR TSARNAEV.   AND FRANKLY,  I WAS WONDERING WHY IT TOOK THOUSANDS OF OFFICERS TO CORNER AND FINALLY CATCH THIS TERRORIST.
