As mentioned above, it depends on the event. Some events have a weapons check area where they will look over your blaster and put a peice of orange tape on the end deeming it safe. A good rule of thumb is If you are walking around with a blaster then I would suggest ensuring that your blaster has an orange tip or orange tape of some sorts. If you are going to be just in a photobooth, then it should be okay to not have an orange tip on your blaster. Personally, I have never been harassed when I have followed this....hope this helps
