I've had it called on my behalf with two of my shootings and for one really long fight my partner and I were involved in. When I finally got the bad guy hooked up, I got on the air with one in custody and need rescue two times once for me and once for my arrestee (screwed up my hand while breaking his face). This is when I learned to keep my motor helmet on when going into calls because I could have just headbutted him and made quick work of it.
I've been working a few times when it was called for other officers. Amazing things what a Crown Vic will actually do when pushed hard.
