Boston attack 8216;easily8217; one-man operation,say bomb experts

Retired FBI bomb technician Kevin G Miles said the attack could 8220;easily8221; have been the work of one person.

8220;A one-man operation could easily do something like this,8221; Miles was quoted as saying by the Boston Herald.

8220;It would take some coordination,some know-how and some intelligence,but a lot of bombers throughout history have been one person.8221;

Miles also said it would have been all too easy for the bomber or bombers to blend in.

8220;There are thousands and thousands of people. You8217;re not going to be able to check everybody8217;s backpack,everybody8217;s gym bag. Every runner8217;s got a backpack8230; We8217;re a free country. This isn8217;t Russia or Cuba.8221;

The white smoke was indicative of a 8220;commercially available explosive,8221; such as smokeless gunpowder,Miles said.

He,however,said there is nothing to immediately indicate whether it was the work of a team or a lone wolf.

While Grant Haber,a security consultant who runs the firm American Innovations,said that when the 8220;terrorist has planned an attack and they8217;re going to utilise an IED as their weapons of strategic influence,it8217;s hard to stop that in a free and open society8221;.

Authorities confirmed nothing about suspects and provided no details about the types of devices used.
