Inoue?

At least the second cut was animated by Inoue (I think the third was too).

そうそう、私です。
この原図は多分そのカットかな、、

その警官のカットを描いたのは「くじらのピーク」が終わってすぐだったので警官ののプロポーションが「ピーク」ぽくなってしまった記憶が、、

If I understand him correctly, he says that he animated these policemen right after Kujira no Peek, so the proportions of the bodies were similar to those of the Peek characters.
