Design Brief for Informal Cites (summary)

In Rio de Janeiro there are many Informal Cities, with many people facing problems of safety. The Rio de Janeiro Informal Cities (slums) are having huge problems with the mass drug war throughout various slums. over 1000 police officers have been asigned to stop the drug dealers, but this lead to violence of the communities in the slums and thus many innocent people got hurt and have a hard time finding safety or medical attention. In these Informal Cities i would like to design buildings to reduce safety problems for all ages.
Some of my solutions are to create recreation areas to get children and adults out of the streets and into a safe surrounding. Another solution is to build a school for children, inorder to give them somthing to do and keep them out of trouble, or i will try to build a community center (centre) in case of unsafe environments. I will create these buildings (what ever one i choose) with re-enforced concrete and heavily guarded, with massive/thick walls that will protect the people on the inside, all the glass will be bullet proof, and every thing will be upgraded in size just for protection. Safety is my main priority.
