Most crimes occur during nighttime hours, that's why it's crucial that you arrange all your activities to be during daytime hours when traveling in Myanmar. Ideally, you should travel why it's cool. Just like any tropical Southeast Asian countries, Myanmar can really hot and humid especially around noon time. It's a good idea to gather and get the group together at the break of dawn, head out and check out the sites, hit the local restaurants and enjoy yourselves before noon time. This way, it's still relatively cool and you enjoy the security of being out in broad daylight.
