Jeez, I live in San Antonio and this is the first I’ve heard of this incident. I will say that by and large, we’re a pretty chill bunch.
See the link in post 15.
The incident happened at some tapas bar near UTSA.
One thing I noticed. This happened at 2:00am after the bars closed. Even in an upscale yuppie neighborhood; bad things can (and do) happen when the bars close.
