The massacre at Viginia Tech

Again, an epic killing spree has been committed again, this time in Blacksburg Virginia. A man who methodically shot and killed at least 30 people on the campus of Virginia Tech, and the whole world reel in the wake of the deadliest shooting in U.S. history.
So far, there are so many questions but very few answers. I hope that this terror act, ’cause that what it is, at least does something with the American gun laws. One of the candidates trying to get the nomination for republican party does the opposite, John McCain says: “I do believe in the constitutional right that everyone has, in the Second Amendment to the Constitution, to carry a weapon”. I cannot understand how a person could support this, when so many deaths has occurred in the last 10 or-so years, shooting people at random. Ban guns now!
