It all depends on where you are. In the rural area where I live, even most cars roll stop signs if it's clear. Police don't care what bicycles do as long as it isn't causing anyone an issue. Near campus in town, where you have a lot of riders who totally blow through stop signs and do cause issues, there is some enforcement but even there coming to a near stop is fine. There are some jurisdictions where enforcement is scrupulous, so observe and speak with fellow cyclists in your area.
