We still live in a free country. Preventing random acts like this is virtually impossible. Homemade bombs can be made relatively easily and cause much damage.Sharing an excellent comment:
"At this point there are only two possibilities. Either the Boston bombing was a false-flag, or it was a real act of terror. Personally, I am leaning towards false-flag; we are just waiting to see who (other than Muslims) gets framed for it. But if this was a genuine act of terror, what it tells us is that DHS, TSA, FBI, CIA, the Fusion centers, are all a complete waste of taxpayer money. All the databases, all the warrantless scanning of our emails, social media, phone calls, all the crotch-grabbing, cameras, microphones, GPS tracking, naked scanners, were totally and completely useless. Even the bomb sniffing dogs, on site in Boston supposedly for a training incident, failed to sniff the bombs. From top to bottom, the entire security industrial complex laid a big fat egg on this one. They failed, simply and utterly. And therefore, there is no more justification for the people of the United States to put up with this erosion of Our Constitutional Rights. Simply on the basis of total incompetence, Boston justifies the firing of the Federal government.
Preventing everyone with a backpack from entering a subway or an open arena or anywhere where there's a crowd and exploding a bomb is just not possible.
We can only monitor plots to a certain extent even though we've managed to disrupt quite a few of them.
But we are always going to be vulnerable. Just like everyone else in a free society.
Obama was just too quick to announce he had the enemy on the run. Another sign of poor leadership and indictative of a heady president.
