The truly sad aspect of the Boston Marathon bombing today is that it won't change anything. The perps will likely be caught and either killed or put away for a long time. If they did it for some as yet unstated cause, that cause will continue to exist beyond them. "Preventative" measures (false faux word)will be instituted. Politicians will wax eloquent about what caused or enabled this. But no hearts will change. No laws will pass. Six months or a year from now the next "terrorist" incident will occur, and we'll be back to square one.
