If they arrested every dude out there for tipping back a High Life there'd be no other time for any other kind of police work. (The wire , tv series)
In this example commissioner is talking about an incident that happened before his time which means this conversation is about possible situation in the past and its possible result in the past not about imagined situation and its possible result in present or future.
The reason why I am confused is that whenever I search about the structure of the second conditionals they express the intent of the second conditional as "We use the second conditional to talk about the possible result of an imagined situation in the present or future" . And in my example second conditional was used for "possible situation in the (past)", like first conditional but this time possible situation and its possible result that we are talking about is in the past .So why do we use second conditional form when the situation is not a hypothetical situation and its results are not in present or future (it is in past)
