Whoooo Nellie, you gotta read this one.
Three weeks before the attack on the 15th the surviving Boston Bomber, Tsarnaev had the following conversation with some of his buddies. They all live in and around Boston MA and study together. Things to take away from this exchange is the timing along with the fact that they were talking about ‘fireworks’ that ‘can do some damage’ and (sic) ‘fuk shit up’ it’s also worth noting that from the conversation we can deduce that there had been some previous ‘tests’ from the phrase ‘I got some more left’.
