"Meet you in 30 minutes." This phrase is constantly being used by Bosch and other police in series. You can't get anywhere in LA in 30 minutes, much less from Hollywood to Santa Monica in "30".
Harry Bosch's home in the Hollywood Hills is a stilt home that would cost (MINIMUM) $1 million. The taxes and upkeep ALONE on such a home would be between $15-25k per year. Given Bosch is a detective and not even a detective sergeant, even with his "TV money" he shouldn't be able to afford live there.
