I've seen a number of pictures that show what looks like safety wire between the pins for the trigger group.
What is the purpose of this?

I'm pretty sure you're seeing KNS anti-rotation pins, not safety wire. These pins prevent the hammer/trigger pins from rotating.
I agree with Mark with regards to their supposed utility. Over the years, I've heard more than a few NFA folks say the pins might help keep the pin holes on your non-replaceable registered lower from "wallowing" out over time. I've yet to see a receiver that was ruined by "wallowed" pin holes, so it's likely just a myth. On a semi-auto rifle, I'd imagine they are simply bling.
However, there is little doubt that these pins will lighten your wallet...which usually leads to higher speed and lower drag on TOS.
useless.
I've seen a lot of well worn Colt 613 and none of them need those KNS pins after many years of abuse
Yep slowly disengage the hammer to relieve some tension. Get a good punch and a gunsmith hammer if you have one. I like to tap from the left to the right, and then right to the left when installing. First the hammer than the trigger.
As Kimbo stated there is a proper way and you just proved my point. When you get a monkey (that's a general term and doesn't necessarily apply to you) with no training trying to pound the trigger pin out while the hammer is still in place it becomes evident. That's because they don't know know that the trigger pin is held in place by the hammer spring. They also don't line up the hammer pin correctly and just try to pound it in because as we all know a bigger hammer is always the right answer.
Add to the mix people using the wrong size punches and other incorrect tools and you can see just how it happens.
