If you're ever going to a protest for anything dangerous/political...a FURSUIT is the perfect gear to wear, and here's why:
-You can easily conceal a basic filtration system into the head snout to repel chemical irritants like tear gas and the like.
-The foam-lined bodies and headbase structure will resist baton attacks from the police if well built. (carbide instead of plastic for example)
-Your identity is automatically concealed to prevent further reprisals from camera-wielding authorities.
-You would be immune to taser attacks as well as possible resistance to beanbag and rubber bullets.
-Your fun sona would inspire peace and joy, confusing the tone of the oppressing force you're protesting. Worked for hippies occasionally!
-If necessary one could ditch the suit in minutes and disappear into the crowd invisibly to escape to safety.
