Rest assured, all lawyers in Canada (we’re not in the U.S.) greatly appreciate the services that first-responders provide. Many in the plaintiff bar would argue that the reason their clients choose litigation is that they require funding for further services to help them recover or maintain a reasonable standard of living.

Why would you want to do this? Oh I see, you see dollar signs. We see injured humans. Can lawyers get any lower? I also believe it is illegal in most states to have a police scanner in your car. The statues vary and also hinge on whether it is “required” for your job. See FL and MN laws. See NYS law quoted here

§ 397. Equipping motor vehicles with radio receiving sets capable of
receiving signals on the frequencies allocated for police use. A
person, not a police officer or peace officer, acting pursuant to his
special duties, who equips a motor vehicle with a radio receiving set
capable of receiving signals on the frequencies allocated for police use
or knowingly uses a motor vehicle so equipped or who in any way
knowingly interferes with the transmission of radio messages by the
police without having first secured a permit so to do from the person
authorized to issue such a permit by the local governing body or board
of the city, town or village in which such person resides, or where such
person resides outside of a city or village in a county having a county
police department by the board of supervisors of such county, is guilty
of a misdemeanor, punishable by a fine not exceeding one thousand
dollars, or imprisonment not exceeding six months, or both. Nothing in
this section contained shall be construed to apply to any person who
holds a valid amateur radio operator’s license issued by the federal
communications commission and who operates a duly licensed portable
mobile transmitter and in connection therewith a receiver or receiving
set on frequencies exclusively allocated by the federal communications
commission to duly licensed radio amateurs.
