“Melrose Police say they received a computer-generated phone call stating there were “shots fired” at the home.”
Computer generated is guaranteed to be bogus no matter what the subject of the call. And they sent the SWAT team out for this?
Sure, an active shooter call should merit an immediate response. However, in the minutes it takes to assemble and transport the SWAT team to the address a simple phone call could provide valuable information. That changes the situation from SWAT breaking down doors with all the potential for loss of life that implies to a knock on the door and a friendly chat with a deputy/officer.
If I got a phone call about some non-existent "incident" at my residence I'd give them the true story. When the sheriff's deputy arrived I'd invite him or her in to see for themselves, have a cup of coffee and a chat, and thank them for their rational response.
SWAT-ing is well enough known that I think law enforcement everywhere has to be suspicious of any call that is trying to elicit a forceful entry into an address that has no history of any kind of crime.
