Corrected entry: The previous movie saw Shredder have a lot of Foot ninjas, maybe over a 100 or more. Here it seems to have shrunk to maybe only a dozen such as having only one helping Karai guard the teleportation device.
Corrected entry: The Turtles are afraid about getting shot by the cops in this movie. But in the previous movie, they found out that they were bulletproof when they were shot by the Foot Clan.
Correction: Still, being shot at is an unpleasant experience, and they may have vulnerable areas on their bodies, such as their eyes.
Correction: And how exactly is this a mistake? He was defeated at the end of the first film and his organization taken down. Not hard to believe that most of the Foot were taken out or arrested and this is just what he has left, or are new recruits.

When? Like most of those Foot the Turtles encountered at Sachs Tower stayed there to be arrested? They weren't locked in by the Turtles.

Even if not all arrested, this is the clan we are talking about. This incarnation of the Foot Clan doesn't exactly work on the honor system. Their leader was gone. This would leave a power vacuum in the ranks. And in fear for themselves, perhaps most of the clan moved on and fled. Many possibilities for this.
