the.com/long arm of the law
The law's reach never shortens, even when your memory conveniently does.
means The far-reaching power of police and legal authority to track someone down and hold them accountable, no matter how far or long they run.
from A straightforward metaphorical phrase from the 1800s, built on the old image of an 'arm' as reach or power (as in 'the arm of government'). To call the law's arm 'long' was simply to say its grip extends farther than wrongdoers hope — into hiding places, across borders, across years. No hidden backstory here: it's a plain personification that caught on because it's so visually apt, and it's stayed in everyday use ever since.
