Based on your dozens of posts on this topic, I do not believe there is any sort of police activity of any type that you would have difficulty commenting on.   Nor do I believe the facts of any police activity would ever play much of a role in your commentary.   I would be surprised if it is actually possible to arrest people who are in the business of selling guns illegally in a totally safe manner.   However, it is probably safer to have the police attempt to arrest the sorts of people who make a business of selling guns illegally than to let them continue in their business.
