[id: Comic drawn in a cartoon style. Text of comic reads: "How to spot a kettle: Police may try to surround the march on all sides in a 'kettle'. If you're kettled, they might hold you there for hours (they often lie about when they're gonna let you go) or even arrest everyone. Look out for a prisoner transport bus. If you see a kettle coming, the safest exit is usually back the way you came." End id.]
