Back in the day, I remember numerous stories of NYPD cops shooting each other and by-standers in bars. I also recall, circa 1980, my first visit to Dallas, at the airport bar (and all drinking establishments in Texas at the time) there were signs reminding patrons that firearms are not allowed in drinking establishments in Texas. (”Check your shootin’ irons at the door, gentleman.”) Good policy.
BTW, why do we need to read about these stories in the British press?
Because we wouldn't read about them at all, otherwise?
