That’s a bad link, but I found the story you’re quoting. Funny, it also includes this information that you left out:

“The franchisee’s statement, issued late in the day, also conflicts with a statement made by Twin Peaks corporate made earlier, that the on site operator was told of law enforcement’s concerns and gave “assurances” that appropriate security measures had been taken.”

So it seems Waco PD and Twin Peaks corporate are telling the same story, while the franchisee (who would be most directly liable in a lawsuit) is the one telling a story nobody else agrees with.

Most likely corporate was simply reciting Swanton’s talking points that dominated the first few days’ news reports.

None of those versions corroborates your original contention.

Your original contention was, "The police tried to stop it but the business owners would not cooperate."
