Do NOT beat me up, but I totally disagree (and expect to catch a lot of flack for it). You are not an employee of this facility so even though it may be a stupid and dangerous practice I feel it really is not your business.
I totally understand the desire to protect patients, but you are off duty at a place that isn't your employer and i think it is a good idea to take a break from having to be the vigilant nurse 24/7.
This is just my opinion - I am ducking so you will need to swing that baseball bat low if you really want to connect with my noggin!
