Elevators are tailor made for events like this. All the bad guy has to do is push the stop button.
We need single sex elevators.
Seriously speaking, I do get the concern with men in women's restrooms, but it's overblown to me and inevitable that as soon as an attack occurred in a e law would be blamed. The fact is attacks have happened in bathrooms for years and years, way before the transgender issue came up. Bad guys gonna be bad guys no matter what the law is.
Don't show me a Fox News type headline as proof. Show me that bathroom attacks have become statistically more common due to transgender laws or that attacks are statistically significantly less likely to happen on states like NC with bathroom laws than in other states. Then we can have a conversation.
I can post a story about person falling off a cruise ship. Does that prove cruise ships are dangerous?
