Last year’s marathon was a tragedy, and it will not shortly be forgotten, but that really doesn't justify doubling the security this year to 3,500 people. Last year’s event was an isolated incident, and the suspects were determined to have acted alone. There is no reason to suspect that anything similar will take place this year, especially after last year. If anything, the likelihood of a bombing should be considerably lower this year due to last year’s bombing. I am all for people to get together and have a good time exercising and rooting on the competitors in a safe matter, but spending thousands of unnecessary dollars is still spending thousands of unnecessary dollars.
