Yes, I get that and applaud the fact that they wanted to go for the realistic "unhappy" ending unlike season 1 where the "good guys" win over the "bad guys", but the way they did it was just horribly written: After killing the Russians and taking all the money Frank and Ray set off. Frank was driving happily away and suddenly Le Wild Mexicans appear out of no where. Ray is supposed to be a cop, he's supposed to know very simple truths. Leaving aside the fact that he has lots of money in his car and he's heading out on a boat, he is still a wanted fugitive, and he should know that the first thing the cops will do is keep an eye on his son in case he tries to contact him. While I do get why they wanted Frank and Ray killed, the plot seemed so forced it's just unrealistic.
