I have to ask how the officers view the carbine in .30 carbine?

In the USA we had a man named Jim Cirillo that was part of the NYPD stakeout squad that had a ton of shootings before the liberals put it out of business. Jim told me that one of their favorite guns was the M1 carbine which was the first gun in .30 carbine and that they had the best success in stopping bad guys with the soft point round in that weapon.
