I get what u mean. And I am talking as if this isn't nucky's first murder. That's a guess tho.
But it leads to my only issue with breaking bad. It's been 5 seasons but only 1 year. Chemistry teacher at 50 to running the empire days after the 51st. I think the first two seasons of boardwalk might have been longer in real time
And I'm not saying mike shouldnt be a goon. But he ain't just killin nikkas and throwing them in a building. Anybody could do that. He's doing things you need HIGHLY trained people to do. Not "a former cop". If they said "former FBI" itd match up a little more. Regular cops cant even outsmart internal affairs most of the time. And if he's a senior citizen then his cop days would have been long ago before they had half the tech or current procedures
It was his first murder. That's why it's supposed to be a big deal. Still don't make any sense.
The sole reason they stuck to the "one year" time line is because he was given a death sentence, "2 years". So it's more for the sake of continuity than being realistic.
Mike is doing more than Chris or Snoop but he also has had 30+ years more than them to learn all the shyt we're talking about. He's a career goon.
According to Saul, Mike knows killers, hit men, all kinds of criminal connects. I doubt the show will spell out Mike's exact back ground besides "ex-cop", but you're probably right, he ain't been a cop in a long, long time, and he's probably been gooning since then.
