Well, it is an obvious vantage point, but that's not my real question about this guy. I'm wondering how, on an apparently limited budget, he gets around so easily and quickly? He seems to have good Intel as well. Now, being a nut, probably obsessive/compulsive, he is scouring the net for as much info as he can day and night, so that may explain his foreknowledge of events relatively unknown to the average Joe. Why would the average Joe give a shit about Trumps schedule, but a would be assassin...he'd know details.
You made reference to Trumps poor judgment and need to be in the limelight even if that puts him in danger. Yes, that's reckless on his part, but his security detail needs to and should accommodate for that. Both of these wanna be assassins got way to close, security was poor and only dumb luck kept them from total failure of keeping Trump safe. I'm sure the pros are watching and learning. These attempts will not stop, and if he's elected will probably increase.
Yes, Trump is his own worst enemy, but they got a job to do and so far it's been sloppy and they've been lucky. That won't hold up forever.
