Just a thought.
Those people who have the tapes and notes that AB has told people about should take great caution in their actions. AB had health issues but no overt immediate problems. Remember the former Russian spy who died as the result of a hit job several years ago. It was just dumb luck that the cause of death was discovered to be something other than natural; turned out to be radiation poisoning from a doctored drink.
Am I saying that Andrew Breitbart was the victim of an assassination? Forsooth! I never said any such thing.
Believe me, when I heard the news the very first thing I thought about was s passerby with an umbrella.
