Santa Ana and crime free are oxymoron.
It is the second or third poorest city on Orange County.
It is the hub of illegal immigration.
The police will not give you the stats. Some websites might.
It is also a victims, yet again, of predatory housing prices. As poor and full of immigrant area it is now targeted for pricing that is higher than it was at the height of the bubble, the last one. Wages and jobs are way down, though.
The result is overcrowding and overcrowding is not crime free.
