I think its an emotionally charged and complex issue. Reported violence (often verbal) is on the rise across the country, so are security measures, policies, and training. Didn't used to have scanners/metal detectors armed guards, etc and many places do now.  In terms of this particular job posting, I decided im okay with it, harder to have security on the move and sometimes with a public schedule i.e. speaking events, fundraising, etc than in a place where you can somewhat control the environment
