Question: is it realistic to expect cops to know exactly what law someone is breaking before they decide to arrest them? Like I get that in an ideal world this would be the case, but humans only have so much memory. Is it unreasonable if a cop arrests someone because it seems the person is doing something that warrants it, but then later fails to find an actual crime they can charge them with? i.e. Would we be better in world where cops only arrested those whom they could immediately charge with a crime?
