as to the original post!!!!!
anytime a POTUS visits anywhere USA, the CIA and Secrete Service are there 2 weeks prior to the visit.
Man hole covers are tack welded down, the bridges, both over and under are inspected along the route and 24 hours prior to the visit the bridges are reinspected and guarded. One patrol car is stationed at each bridge 24 hours in advance and during the visit and not to mention all the stuff we don't see. Snipers along the route, medical staff cleared before arrival, planned escape routes...blah,blah,blah,.
There is a ton of security before any visit. it cost tax payers an average of $500,000 per visit (includes security, Air Force One and so on)
These guy don't protect NObama, nor did they Protect Bush or Clinton. they protect the President of the United States, they don't care what the persons name is.
