The ruling class in Iran made the same comparison; perhaps before CBS did.
It's not all that inapt, really. Sometimes the government uses excessive force, and that includes the US government (and sometimes smaller players, like local cops, etc.)
It's unacceptable conduct by the government, but governments get away with it, and for the most part, so do the individual actors in the government who use excessive force.
When we need fraudulent “moral” advice from Iranian mullahs or phony “moral equivalency” from anyone, we will be sure to let them be the first to know. Meanwhile, they ought not hold their breath.
