Please explain the ending (Obvious Spoilers)
I've only seen the first movie, so I don't know if my questions are explained in the other two movies, but here goes. So I gathered that Dawson killed Paula, which is why Eddie Dunford dude blew him away at the end. But was Dawson also the child killer? I remember there being talk about someone mutilating swans or geese, and then Dunford found one at Dawson's apartment. I'm also not sure why Dawson killed Paula, was it to frame Dunford?
And why did the corrupt cops give Dunford the gun? I kinda figured they assumed he was just gonna top himself, but I don't think that takes six bullets. I'm pretty sure Dunford shot one of those cops at the bar right afterwards. It seems odd that they'd beat the hell out of a guy whose special lady friend just got killed, then give him a loaded gun and assume that they'd remain unscathed. WTF?
