Daily News caused quite a stir last week at city hall when they released a database containing every city employee's salary, save for sworn employees (ex. police, fire). You can browse by department or look up by name. Have a friend who works too hard? Now you know they need a raise. Deal with an irritable city employee over the phone recently? Maybe they're overpaid.
Now, starting today, thanks to Daily News crime blogger, Jason Kandel, readers can look up people arrested in your neighborhood. So far, the database only shows who got arrested on Sunday, May 18th and according to those listings, a total of 290 people were arrested in Los Angeles yesterday. From attempted murder to DUIs, it's all there. However, the paper duly notes that "each person in this database is a suspect only and is considered innocent until proven guilty in court."
It's unknown if this will be a routinely updated information portal or not, but it does highlight what the LAPD is doing at some level. 290 -- that's seems like a lot of arrests, but it's a trend not often studied in the public eye. How many people will be arrested today?
