Didn't Manny have some of his own people? Why did he try to murder Jimmy personally? And why was Doyle able to just walk up to his home? they only showed one man that worked with manny, and he's sleeping with the fishes...or beef. i guess he takes getting shot really personal. were you expecting the corleone compound type security?  I don't know about a compound  but I would have thought after getting shot he wouldn't let people just walk up to his house.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming
Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
