I hate to think what a criminal could do with that weapon.
Like, break into someone's house while they are asleep, and shoot them in their beds? That's exactly what the Denver SWAT team did to one Mr. Mena a few years ago. Probably with H&K MP5s. One or two jurisdictions over. (It was a wrong-address no-knock.)
Nothing that a criminal couldn't do with any other weapon. It isn't the weapon it's the criminal
As opposed what a highly trained SWAT team member could do if he was charged with confiscating your guns?
The next time somebody shoots at me I sincerely hope he's on full auto. That means he gets to miss that much faster. There is a specific (well several) pattern that one should use when using full auto to take advantage of muzzle climb. I used to use the low/high method of deliberately aiming low and stitching a neat vertical group right up the front of a target. That puts more effective rounds on target than off. When engaging a vehicle, you can go with the "Z" pattern that starts off to the rear of the vehicle and rakes the fire laterally across the target LOW from rear to front then shifting at the front to an upward cant of the pattern again raking the vehicle from low front to high rear and then a third swipe this time at the top from rear to front again. Each burst should be between 7-10 rds. When dealing with a vehicle it almost always works better to be using something like an M2HB cal 50 that something like the MP5.
OTOH the M16 got the gift of the (hated) three round burst limiting device because spray and pray had become the norm and that was a scary thing when entering a tightly packed room with other soldiers and attempting to neutralize multiple targets. That's why we invented the technique to split the room into halves with one high and one low sweeping to intersect at the middle. The H&K MP5 Suppressed is IDEAL for this situation.
