As I was reading the PDF, I came across something that I found extremely interesting in that it apparently had Mtn Jack's incident in mind...
"An officer who observes a person who is engaged in the open carrying of a
firearm in the vicinity of a public event attended by the President or other persons
under the protection of the Secret Service must consider whether any violation of
Pennsylvania law is occurring, If there is not a clear violation of the law, it would
be prudent to bring the presence of this person to the attention of the Secret Service
who is empowered under various federal statutes to regulate the possession of
firearms in the vicinity of persons under Secret Service protection."
See...(#204) below...Guess I missed another reference...gotta keep me mouth shut... or read all other entries...Gee bet others would do good to do this
