There has been quite a bit of consideration of the application of 'zero tolerance' policies doing rather more harm than good.

It has been observed that it is important to crack down hard and consistently on what is called 'quality of life' problems. In the case I mentioned, erasing graffiti means no gang tagging, and sends a message to gangs that gang activity is not tolerated. Give gangs an inch and they will take a mile. Same goes for men inclined to dominate a workplace and create a hostile environment for women, gay people, etc.
The misogynistic 'banter' that so many women (and gay people) have to put up with because it's considered low level - and therefore completely acceptable, something they should be willing to put up with in exchange for the privilege of being let out to work - is a form of turf marking in exactly the way gangs tagging turf is. It's one group of people (men) making it plain that the office is run on their terms in order to make sure another group of people knows its place.
I live in a well run, very racially and economically diverse municipality where property taxes pay for excellent public schools which provide a vast range of support services for struggling students (academic, social-emotional, support for students who are parents/creche in the school, a discipline policy aimed at eliminating detentions and suspensions) along with great public recreational facilities, libraries, and outreach and youth programmes run by police, park district, and the public health department.
An integrated and consensus driven approach to issues is not only possible, it's the only way to ensure results. The result in the case of the place where I live is solid, community-wide support for police and policing, for school administrations, and willingness to shoulder the tax burden that makes it all possible.
There is an 11pm curfew for under 18s. Parks are off limits after 10pm. I can take a walk outdoors any time, day or night, in my neighbourhood. I could leave children's toys out on my front lawn (which had no fence or wall around it as in many American municipalities) all night when my DCs were young. I often leave my back door unlocked at night.
This is a very nice place for children to grow up and form their opinions of the world and their place in it. It's a high trust society with a high degree of trust in the institutions that keep it ticking over, thanks to zero tolerance and the other elements that go hand in hand with it.
