After the Boston Marathon bombing, communities across the nation are rethinking how to deal with events that draw massive crowds, such as San Francisco's Bay to Breakers race scheduled next month.
As the Examiner notes this morning, San Francisco police and race organizers are already rolling out a new set of rules, including no more backpacks.
We know what you're thinking -- where are you going to surreptitiously stow your beers now?
It'll be difficult, since you also can't bring large bags or any type of container or carrier exceeding 8½-by-11-by-4 inches.
The reason for these specific changes are quite obvious: The two suspects in Boston carried bombs inside backpacks; the attackers placed the two bags on the ground near the masses standing at the finish line of the Boston Marathon. Both bombs exploded, killing three people and wounding more than 180 more.
"The Boston Marathon bombings have raised the public's awareness of potential attacks," Police Chief Greg Suhr said in a statement to the Examiner. "It has reminded the public to have a heightened sense of awareness. We are asking observers and participants to be attentive on race day and report unattended items such as backpacks and packages."
On top of the no-bags law, organizers are seriously cracking down on those rogue runners who don't register but show up on race day anyway. Every year, only half of those who participate in the annual footrace have registered.
To be sure everyone who is running has a bib, and all backpacks are left at home, there will be more cops -- a lot more -- roving the streets on race day.
