He didn't enact it, but it was a signature policy of his, and he pushed it hard. There were twice as many stops his final year in office as there were his first year. It is only a reduction if you compare it to his penultimate year, when there were 7x as many stops as his first year.

This claim he reduced it is a key talking point of his campaign, and an outright lie. He was defending it literally up until the moment he decided to run for president (defending it publicly for years until October 2019, then apologizing in November 2019 when he announced his campaign).

> and he stopped it.

Assume what you want, but that claim is just false. He also defended it for years even after it was ruled unconstitutional.

Stop and frisk is only the tip of the iceberg, by the way.

Lol he greatly expanded it, what are you talking about.
