Now always. Depends on the lockup and the "suicide risk assessment" (and the competency of those making the assessment) at intake.
There is no uniform policy.

All my jails (3 county) do it. And no, I don't know that because I accepted their hospitality. I was there in a professional capacity. So I think there should be an uniform policy.
Our local jail has had about 4 high profile suicides in the past few years. Bedsheets, every one. And the families are suing the jail...unsuccessful thus far. Ridiculous.
