@michaelsierraa @TexasMonthly Cool article! I can see how you used some researcher skills to get this done. Curious about how this came about and how you squared it with your academic role (e.g., clear it with admin/IRB) ?

As the legal dust settles at Lunada Bay, will the notorious Bay Boys finally share the waves? I examined the surf gang's 60 year reign to try and figure out the next chapter of history at SoCal's most fiercely localized break. Spoiler: it could be gnarly

@keribla 😅 can’t let pesky implementation details get in the way

Today the LASD anounced a policy officially banning deputy gangs - and a lot of people are not happy!

Civilian oversight officials say it ignores most of their recs; Inspector General says it was done in secret & the ex-sheriff says it's a "fake" policy. https://t.co/f4CrOaTZtb

@ProfFerguson @politico When FR first started being used, some depts didn’t know officers were using free trials of that either

@Catherineoscopy I’m guessing he hasn’t done or read research on *exactly what he just did* and how weird that is?

[Sam Peterson @_SamPeterson]

@keribla That’s a good one. Have you read the old OIR and special counsel reports yet? I have those in searchable pdf

So many interesting questions on this… it’s such an obvious use case, and yet so problematic.

'experiences of police violence predicted future confrontational actions via heightened motivations for non-normative resistance and increased risk perceptions... coercive police violence ... can contribute to the radicalization of protesters.'

For months, I'd been hearing rumors about people w/alleged deputy gang tats getting them covered so they could get promoted.

Finally, @LASDHQ let me interview one of them: The new chief of the Detective Division, who once had a Banditos tattoo.

@keribla @MrPissant @LASDHQ We definitely heard from some deputies in our research who felt the meaning had changed after they left the station and wanted nothing to do with it anymore. Can still read into what that means in a variety of ways

@eedugdale @JusticeLANow They need to update their protocol

[Sam Peterson @_SamPeterson]

@michaelsierraa @eedugdale @keribla @JusticeLANow They keep doing this at demonstrations…

@keribla Someone should do a research study on PRAs across agencies

[@cerisecastle.bsky.social @cerisecastle]

Sources close to the matter tell me a potential CA Dept. of Justice takeover stems from a settlement with the department in a pattern and practices investigation opened by then Attorney General Xavier Becerra.

I will be tuning in!
