I sent my self through the academy. The police chief at the time said that he wouldn't supply anything, cruiser, shotgun, nothing. I was kind of worried what would happen. I know that in the packet you get from the academy it says no borrowing of cruisers. Just make friends in the academy. I hopped in cruisers with other guys from other depts. Some chiefs give their recruits strict instructions not to let anyone else drive, liability I guess. Just makes some friends and hop in with someone else. I had no problem. Weymouth does have a couple old SP cruisers there that they sometimes use, if they run. As for the shot gun, last I knew the training council doesn't even do shot gun qualifying in the academy, just the hand gun. I never had to bring one. They do a basic overview of the shot gun, but we were never required to bring one. My buddy just graduated from Boylston in March and they didn't get certified in the shot gun and weren't required to bring one. When I was in the academy they told me that they leave it up to individual depts to certify their officers in the shot gun, they said that every dept doesnt always have a shot gun in each cruiser so they leave it up to the dept.
Good luck
