Safety in my neighborhood

Nowadays I've got really scared of walking alone in my neighborhood cause I've been listening to a lot of terrible things that're happening around it. I used to go walking from my house to almost every places that I go, like the gym, school, my friends house, restaurants, and etc. And even in the weekends sometimes I used to meet up my friends in bars on the streets ang things like that. But now almost every week I hear about people being mugged, being stalked by homelass men and even being shot. That is really shocking to me because my neighborhood use to be really safe and calm and I used to fell confortable and secure there. Maybe me and my family should gether all the neighbors to require for more safety and surveillance around us.
