Do you think William H Macys character was going to be killed?

So near the end when they are at the Pier, the corrupt detective tells one of his goons to take Macys character to the hospital for his neck wound, on his way Macys character overhears the thugs on their Walkie Talkie and realizes they are all corrupt and part of the Kidnapping.

If Macy never heard that and did not realize what was going to happen or of the corrupt cops, do you think his partner was going to have him killed just for knowing some stuff? I mean he already was retired.

We already know Evans character and the Martins were to be killed now that the tape was destroyed, but I wondered if The Corrupt cop friend was to have Macy killed as well just for knowing some knowledge
