And it’s working ... there was a report that Pres. Trump would be showing up in our area & my mom begged my sister and me not to go, fearing a shooter or other attack.
It looks like he is not going to be there now, but I was considering going, until Mom got so upset.
I think the idea of a substance smeared on railings or something like that makes more sense than other theories. It could have been someone walking down the stairs and holding a cloth along the railing as he left the venue a bit earlier than others. Wouldn’t be as obvious as someone holding/pointing a laser in the audience & not everyone would touch the railing as much (or at all), so some would get a stronger amount, explaining the varied symptoms & effects and when they manifested.
