That is property desecration? First off desecration is treating a sacred place with violence, so you are using the word wrong. Secondly laser tag guns shoot just that, lasers. Lasers are light, they don't damage any thing. The only damage that will occur is damage that will come from the participants physical movements. There are many other activities that have that much and even more possible physical damage that you don't mention. What about airsoft? That can actually cause physical damage to property and people. Don't mention something that brings no merit to your argument.
