They come from time to time just to reinforce the narrative as they massage your mind:
"A Littleton man found white powder inside a “threatening letter” on Tuesday, sparking a hazardous-materials response from local, state, and federal authorities, officials said. The man, whom police did not identify, is the owner of Prochem Inc. on Great Road; he brought the letter and the powder to the Littleton Police Department at about 4:30 p.m., according to John M. Guilfoil, a police spokesman. The Police Department building was initially evacuated, and the business owner was isolated along with two police officers out of “an abundance of caution.” State Police determined the substance was not dangerous, Guilfoil said."
Was it all just a drill?
