I just think we need to step up security at all public events, I just wish I had a TARDIS and could go back and stop it from happening
Doing that solves nothing. It's been shown time and again that even after all the upgrades, changes in policy, etc. after 9/11, that it is still relatively simple to get things thru security. Where there's a will, there's a way. The problem is that terrorists, whether homegrown or imported, attempt to exploit our basic fears to push us into a position where we're willing to give up certain liberties for the false belief that we'll somehow be safer. Trying to find the end all solution to terrorists, is essentially the same game with hackers. Build a better mousetrap, and they'll just build a better mouse.
The problem is only made exponentially worse in this day and age where information spreads like wildfire, whether true or otherwise. News agencies only serve to incite the issue further. Gone are the days where journalists actually investigate. Instead they bring on any so-called sudden "expert" to give their uninformed, biased opinion on the matter, based solely on whatever rumors are floating around in the media at the time. If you haven't seen John Stewart's clip from yesterday where he grills CNN for their utter bullshit reporting, then you owe yourself a favor to do so. CNN was lambasting themselves in their "exclusive" inside news that a suspect was in custody, only to have to backtrack on themselves and hour later and then blame their "trusted sources" for the misleading information.
Unfortunately when it comes to media outlets, it's purely a numbers game for viewership. Accountability means nothing. Much like the terrorists, they finely craft their language and wording so as to ensure maximum viewership by poking at our fears and insecurities. Notice how quickly the word Muslim came up right after the bombing. Hey, it was on US soil right? What other group is there to easily scapegoat this on? Even though they'll quickly come back with "but that's just speculation, obviously we'll have to wait for the facts to come to light". But the damage is already done at that point. They know full well that those who already operate under the impression that every Muslim is likely the next suicide bomber will take that clip and twist it and spread it on as "it was one of them Muslims, they just said so on the news!". There is no integrity in news any more, but it's kind of hard for there to be when you have individuals such as Rupert Murdoch who control a commanding percentage of all media outlets.
I would say it amazes me how many people automatically assume that just because somebody declares themself as a Muslim that they have immediate suspicions about the individual, but it doesn't. If history has shown us anything, it's that mankind will always ostracize what it either doesn't like/accept or understand. We can condemn groups like the Westboro Baptist Church and the hatred they try to spread, ironic for bunch of supposed God fearing folks, but that mindset will always exist in some portion of society regardless of how many rally against it. All that we can do is keep up the good fight so to speak, and continue to be good to one another. If there is any shining point to be taken from the Boston bombing, it is that regardless of the all the hate and despair you see in the daily news stories, it's that there are still plenty of good people in the world, willing to rush in and help their fellow man in a time of need.
