Huge public events

Yesterday, at the finish line of the Boston Marthon 2 seperate bombs went off. As yet, the reports are sketchy. The news reports say that 2 were killed and many were injured.
Thus far, there has not been any release of information as to who the suspects may be, if any. It doesn't matter, this is truly an act of terror. Terrorists must be punished for these actions, no matter what their agenda, origins, nationality or religion. For all we know, it could have been a bunch of Boston residents upset about the traffic issues associated with the marathon. But I doubt it.
There are acts of terrorism carried out every day all over the world. Unless one pays attention to international unbiased news (Is ther such a thing?), they would not be able to fathom the extent evil activities around the world. As long as there are people that are considered different from other people, whether sex, color, age, religion, national origin, sexual prefrence,or education, it doesn't matter to those that have the intent of violence. These will always be a justified (in their minds). There are people that just feel they must do violence to anyone different from themselves. Basically, there will always be some form of terrorism going on for all time.
We, as a people, must learn to be more tolerant towards others. I truly feel that the people of the United States of America for the most part exhibit the most tolerant lifestyles. True, it has not always been that way. But in the last 225 years, more or less, this nations people have been a part of an ever evolving country. A country that is based on freedom and tolerance.
Tolerance of differences, as long as those differences do not infringe upon the freedoms of others.
We as a nation must be diligent to ensure that our freedoms are protected and that those that would preform acts of terror to  take those freedoms away from us are punished. How can someone from a country of no tolerance be so judgemental of a country that allows its citizens to express their freedoms, even if it includes complaing about the government and its leaders? There are countries around the world that have a zero tolerance towards its own citizens. Those same citizens have very few freedoms and certainly would be punished severly if they were to speak out against the leaders, their military or their laws that inhibit freedom.
We must also consider that terrorists may not always have an agenda, perhaps they are just mentally deficient and incapable of grasping what they are doing. They may not even accept the consequences of their actions.

Actions like these bombs causes one to take pause and wonder about the safety of attending or participating in an event like the Boston Marathon. If fear rules our lives, the trerrorists have already made a small victory. 
Be diligent, if you "SEE SOMETHING, SAY SOMETHING". As a nation, we are still on alert to watch for acts of violence wheter just criminal or actually terroristic in nature.
