Another squirrel in this case, that helps the opening side by making the debate generally easier for them, is to add unreasonable exceptions to the motion.
For example, defending "dissolving the police" except in cases where it has to "uphold the law" is rather easy.
In competitive debating, judges usually consider a squirrel a negative thing.
There is, however, no clear standard on what constitutes a squirrel, and the judges have to decide this on their own.
These cases are rare and will typically win the round for the affirmative team.
