Honestly, if they were spraypainting surfaces that are not theirs, I would be fine with police intervention. I view that as vandalism, but with the caveat that leftists are disciplined for it as well.
Also, I find it very hard to side with people who have masks on their faces. I have a major issue with that.
It’s a lousy article, because it’s hard to tell exactly what the men were doing. The article mentions “racist” posters, but the only poster that is quoted is NOT racist. And they mention the can of spray paint, but do not mention if it was used to spray graffiti. And they do not mention where the posters were being hung, whether it was or was not legal to be hanging them. And it’s not clear whether they were brandishing their “weapons,” but merely had them concealed.
