Good old liberal cesspit San Fran. She'd be alive today if this so called 'sanctuary city' rubbish didn't exist. 5 times lol.
Actually one of the main reasons you have "sanctuary cities" is because law enforcement have found that having people scared to talk to them about "local" law breaking tends to make it much harder to do their job, and this weird idea that everyone should be able to access the law*.
For example if someone has raped an illegal immigrant (and that person is unlikely to have just done it to an illegal immigrant), you, as law enforcement really want that victim to come forward, if just to prevent it happening to a legal resident, it also creates a situation where anyone who looks/sounds like an immigrant is more uncomfortable dealing with the police, and those who know or have family/loved ones who are illegals are unlikely to help the police with unrelated crimes for fear of drawing attention to their friends/family.
There have been cases since Trump issued his orders to round up the illegals where people acting as witnesses, or who were victims of serious crimes have been arrested at the courthouse when they've gone to give evidence (in at least one documented serious domestic violence case the victim was an illegal, the suspect was legal, he called the ICS to get them to arrest her in order that he could try and avoid being convicted).
When you've got the likes of NYC police complaining that ICS raids are making it harder for them to catch serious criminals (not just those that have overstayed a visa etc), you should start to realise that there may be reasons why areas think it's better to concentrate their law enforcement efforts on serious criminals.
Sheriff Joe, the beloved of the anti immigrant crowd (lets not play the "illegal immigrant crowd card" given he target anyone with a mexican look/sound) had a clear up rate of rapes and child abuse that was exceptional - mainly in that so many cases were "cleared" without actually doing any investigations, including no statements from victims or suspects in many instances - he decided possible illegal immigrants were a higher priority than dealing with rapists and child abusers who were white**.
*There have been studies that show that the average illegal immigrant in the US is less likely to commit crimes because they really don't want the attention of the law, so are less likely to cause trouble, and more likely to do things like pay their bills on time.
**Something like 400 cases where rape allegations were mishandled in a 3 or 3 year period, including one where a 13 year old was abused, reported the abuse and had it ignored, only to be abused again by the same person (I think his department paid out over $3 million for that little blunder).
