I've put it in this forum instead of the Police forum where the discussion originated, because I think it is an RP-issue that everyone should consider, not just a police one.

Here's my revised idea about how arrest and bail in DE might work, in two versions, a do-it-now, and a how-about-this?

Do-it-now.

We have the Dead End Group channel for 911 calls. It could also be used to make a request for a solicitor, along the lines of

Dubious Perp: Umm, I've been arrested, I'm in the cells at Deadend and need a solicitor, the custody officer is Officer Dibbelle
Weasel Wurdz: OK, Dubious, I'm in the area, I'll speak to the officer and arrange a visit as soon as I can.

Weasel Wurdz then IM's Officer Dibbelle and asks for sat-nav coordinates, arrives at the DE station, talks to the officer and client, and negotiates dropping the charges, or release on bail, or even telling Dubious Perp that their best defense will be an insane plea, in which case they stay where they are or go to the Paine Asylum.

Note that Dubious does not have to say to the world what the charges or circumstances are.
Note also that Dubious is allowed a single call, just as happens in many police stations. Blasting the group channel with fatuous comments can be dealt with in the same way as misuse of 911 calls.

The advantages are

1) No extra group needed
2) The message will get out to everyone on the group channel, and anybody feeling a bit bored or left-out has the chance to jump in for a bit of RP
3) It will look slick and organised, (well, to the same extent as our emergency services are), but can be implemented immediately with very little work
4) It can be overseen and managed by existing admins without the need to monitor an extra channel.
5) There is a potential for extended RP if the solicitor puts up the bail and Dubious Perp absconds, Weasel Wurdz can then go hunting down Dubious Perp, or employ a Bounty-hunter to locate and play Merchant of Venice with them.

How-about-this?

A bail-credit bank is set up, held centrally by someone like Nadir/Bebe
All DE members are given an initial allocation of bail credits.
Once arrested, bail is set by the police according to a pre-agreed scale.
If Dubious Perp has the credit, they are granted bail, and their account is debited
If they don't, they need to get the services of a bail-bondsman, who advances the required amount, after securing adequate conditions from Dubious Perp for repayment.
Topup Bail-credits may be PR-ed for by being bought, cajoled, extorted from terrified victims, swapped (anything except stolen or forged).

Again, although slightly complicated, it opens up the way for another level of players, businesses, in-game dealing. And it adds a missing level of realism to the arrest procedure that is currently lacking.

It does of course require a bit of thought, prototyping, and implementation.
