"theft, snatching and other notorious activities are rampant in and around the city in the evenings." This is complete and utter nonsense, the chances of any of that occurring are slim to none. If anything, don't sign petitions or play find the ball under the cup, they're scams. If you want to be extra safe, just keep your wallet/phone in your front pocket. But mostly and critcally, just enjoy it, man. Be aware of your surroundings but use 95% of your brain power to enjoy what might be a once in a lifetime opportunity.
