In the US, crisis lines often use the same call tracing software the police use, so you don't even necessarily have to tell them where you're located for them to send the cops after you. I've also had them trick me into giving them a phone number ("In case we get disconnected") so they could send the cops after me.

The police response you get, if the crisis line sends them, can vary drastically based on your area, how well they train the officers to deal with mental health issues, and the individual officer.

I'm generally more trusting of peer-run warm lines. Peer counselors are generally less likely to panic and call the cops, and those warm lines generally don't have the funding to buy call tracing programs. The problem with warm lines is that they're not available in a lot of areas, and they often have very limited hours.

Recently, when my local peer-run warm line wasn't available and I was having a serious suicidal crisis, I called three different crisis lines and tried an online crisis chat. Not a single one of them had anyone available to talk to me, which just reinforced the belief that I didn't matter and my life wasn't worth saving.
