Immediately after the bombings in Boston, the main stream media questioned a radical right connection and the conservative media jumped to an Arab or al Qaeda connection.  It appears that a false narrative is coming from both sides, and still we know nothing except that three were killed and over 130 injured.  With such an international event going on it would be probable that surveillance cameras would have captured some valuable intelligence that can be investigated.  I hope this is the case and we can find out who did it and why.  Such heinous acts must never be exploited for political purposes.
