In the very real sense that laws are regulations. Calls to SWAT are regulated through the law and backed by the force of the state. The mechanism is regulated by punitive measures after the fact, rather than some sort of regulatory filter, due to the nature of emergency telephone services.

I can't understand why this is down-voted. Maybe this is just an emotive issue; somebadguy's aggressive comment makes me think so.

Guns, cars explosives etc are things, and it is possible to regulate their possession wrt individuals that may misuse them.

A call to the police is a service, and is not the same kind of thing since anyone might witness a crime and need to call the police, even unreliable individuals; whereas few people need explosives (esp without a demonstrable need or credentials), and depriving an unreliable individual of e.g guns or a car, is unlikely to be as harmful to third-parties as limiting access to the services of the police.
