I grew up here, I can explain why the city council is seeking this.
A few years back the city implemented huge cuts to it's police department in salary and benefits. Before the cuts, we had 1400 officers (not bad for a city of a million people) After the cuts our police has dropped as low as 700 officers.
With a reduction in the number of officers we have, bay area criminals have taken it as a "Vacancy" sign to do business here. Every type of crime has shot up. Violent crimes, we're a magnet for package theft, prostitution runs rampant, with one spot having as many as 50 girls walking one particular street corner, and car theft.
San Jose just voted to restore some of the pay last week, but it still won't be anywhere near 2010 levels. Cops continue to leave.
So now San Jose is in a situation of having to make due with what they have. Cops won't even consider this place for a job any more. Since they can't get another 700 officers to replace the ones lost, they're leveraging technology to fill the gap. Myself, and many other residents welcome any effort to clean up the streets.
