Ya I kind of agree that his security guys need to remain vigilant no matter what, but I do think you need to give them a little leeway as this is likely not considered a high or even medium threat area. Probably ranked at 'unlikely' and security can actually look pretty douchey if they are trying to act like every event is a high threat event.
Heck this was our 62 year old Prime Minister at the time, years ago, giving a Protestor what became known as the
Shawinigan Handshake
when the protestor used a friendly crowd event to push up into the PM's face and start insulting him, with his security detail just behind him.
Soyboy got easily manhandled by the PM who got a 10:7 round on Cecil Peoples score card even though the ref cited him for holding the choke too long.
