Saw this on TV around 1978; pretty sure it was in color. ALL I remember is that there’s a woman lying on a raft in a pool, in a bikini, I think, and you see a sniper get ready to shoot her; he does, and then you see her lying dead on her raft. Probably an American movie. Heck maybe it wasn’t even a movie. But it’s one of my earliest memories of all (nice, right?) and I’d just love to know what it’s from! Thanks!
Zero In and Scream (1971)?

“Dirty Harry”(1971)?
There’s no raft, but it sounds similar to the opening pool scene. Here is the scene.
