It "sounds" to me (based on the article) that the protesters told the LEOs and or the secret service what was going on ahead of time so they would be prepared so that a scene wouldn't ensue. The one time I saw an armed person try to get near a SS DPS protected event it didn't go well for the person that tried it.
Well that and the fact the moron 'resisted' and did some other not so smart things..But I digress. I'd be willing to bet though that the CAT folks were a millisecond from being ready to intervene should that be needed.
