Violating the privacy of 100% of patrons, putting them ALL at risk, to be able to catch the small percentage of violent people is not an acceptable trade-off, whether the group is 100 people or all of society. This is why we have the presumption of innocence and the 4th amendment. Private businesses can act otherwise, but they’re douchebags if they do so.

Showing ID doesn’t make anyone safer; indeed your bar violated everyone’s privacy and on multiple occasions someone STILL got stabbed. Worst of all options. It makes everyone less safe.

Privacy is a basic right.

Don’t give a single dime to organizations that act otherwise.
