Only if they struck bone. I don’t know for certain but I doubt LE uses soft tip ammo. I would expect FMJ which would tend less to fragment. Even soft tip has a thicker base of copper to retain as much mass as possible. The idea with soft tip is to get maximal expansion and retain as much energy as possible in the target and not lose energy out the exit wound. The Hollywood misconception is that persons struck by firearms violently fly back off their feet at the impact. One day hunting deer I hit a 100 lb doe broadside at ten feet with 12 ga. 3 inch 00 buck. 18 .30 cal. Lead pellets. She did stop walking mid stride but other than a dying shudder on her feet she didn’t move a cm. away from me. Few of the pellets passed through. If one is wearing armor and receives a round impact on the armor you probably would be knocked down or at least knocked back some.
During the Civil War the logistics guys had to evaluate potential new weapons for service. The test they devised was to hang cadavers up and shoot them. It was felt that to be acceptable in performance if the impact had to swing the cadaver back 45 degrees. The thought being that this would knock the victim down taking him out of the fight. Interesting in that it reveals the lack of real understanding about terminal ballistics. Critics pointed out that these cadavers were largely soldiers that had died from diarrhea which were available in abundance and hence the hydration of the cadavers was significantly less such that concluding their was equivalence between them and live soldiers was far less than assumed.
I don’t know what Tx or Waco uses but here is a MA study that recommends the .223 FMJ.
In the study they point out that even the FMJ starts to tumble at about 4.5 inches penetration and then will most likely fragment.
Only the bonded tactical bullet tends to hold together.
