The only problem with scheduling a bill is the Speaker of the House or the Senator Leader doesn't schedule it. They are the gatekeepers of all bill that go to the floor.
It's a bit more complex than that, but yes--they have significant influence on what bills progress and which ones even get a hearing in committee.
In this case, the bill was never assigned to the right committee--it remained in Rules instead of being moved to the Judiciary - Criminal committee.
