The scene is 15 stories up in a luxury office,
The good guys and bad guys have a gun fight.

Automatic weapons fire go through the ceiling.

But it turns out that there is a roof top swimming pool,
The sots go through the bottom of the pool.
And starts leaking in too the offices below.

After numerous additional shoots pierce the pool
The whole pool bottom gives away ,
Flooding the entire floor below.

That's all I got

Perhaps "6 Underground", the Ryan Reynolds action movie on Netflix from a couple years back? It has a penthouse office gunfight that involves a shattering rooftop pool and subsequent flood:

I checked out some info ,
I don't think that was it.
It
Was day light and
a helicopter
was showing this happen on a live feed on tv

Maybe wth black cop and a white cop
Buddy movie?

Beverly Hills Cop?

Showtime with Eddie Murphy and De Niro?

^^^ that sure fits the description. If that ain’t it I wouldn’t know what was.

DING,DING,DING, DING

Last cub scout
For the win.
