I have tried through the various threads on the topic to be specific and cite sources and the law for a reason. I happen to be a Missouri lawyer (aw shucks), although I have not practiced there in 35 years. I grew up in St. Louis County (where I was a law enforcement cadet), and my grandmother lived on McPherson (you'll see it on the map). I lived in that neighborhood while in law school, on Waterman (again, map). So I'm familiar with the neighborhood dynamics.
Delmar (map) used to be the dividing line between the "good" parts of town (white/rich) and the "others" (read black), but the expense of keeping up mansions, and even modest neighborhoods, drove white flight to the suburbs until the mid-eighties when well-to-do yuppies began the re-gentrification process. The McCloskeys were part of that trend.
Portland Place, and the surrounding blocks, were part of an earlier trend in St. Louis of creating exclusive (VERY white, by law - Jim Crow was very active in st. Louis) enclaves in the early twentieth century. St. Louis and St. Louis County are historically one of the most segregated regions of the country.
The story of segregation in St. Louis. That's the background for this situation.
Mayor Krewson lives in an adjacent neighborhood. About 4 blocks from Portland Place. As previously noted, her street does not connect to Kingshighway (see history), so the
protesters heading up Kingshighway took the most direct route they could to get to her house. One of the local preachers led the way. The gate was not damaged, as I've noted, upon their entry - video clearly shows and contemporaneous news reports verify. I've no doubt that the crowd was boisterous, but there is no evidence - none - that they were violent. Nor, is there evidence they ever threatened the McCloskeys, other than their self-serving declarations. Mark McCloskey himself admitted that he previously pulled a gun on another unarmed resident that he perceived was "trespassing". That's their only justification, here, too. But, again, there is no evidence the crowd ever entered their property, nor intended to.
There is no legal question that their actions constitute "brandishing" under the previously cited Missouri law. It's textbook.
What's left? The trial, I suppose, where they can present their defense. But enough of making up facts and pretend laws.
