flag-burning

Flag desecration or flag burning is a term applied to the desecration of flags or violation of flag protocol, a various set of acts that intentionally destroy, damage, or mutilate a flag in public. Often, in case of a national flag, such action is intended to make a political point against a country or its policies. Some countries have laws forbidding methods of destruction (such as burning in public) or forbidding particular uses (such as for commercial purposes); such laws may distinguish between desecration of the country's own national flag and flags of other countries https://en.wikipedia.org/wiki/Flag_desecration
