Protest against criminality

Hello. I am from Sweden, but I want to make a protest in Austin texas against criminality in your city. I dont know how much criminality there is there or anything, but 1 crime is 1 crime too much. I don't know american timezones so you guys are gonna have to pick a time, I also dont know the city at all so you guys decide a meeting spot for this protest. And my English isnt adequate enough to spread the word so you guys will spread the word, design and put up flyers (fliers?) etc. Also make some signs saying "stop robbing people", "crime has to stop" so the criminals understand

Lets go guys, this has to stop.
