Leon's men were cornered. They were stuck in the middle of the corridor and their only way to get out of there was to use Hailee as their hostage. Therefore, when the police tried to get closer, they became increasingly panicked and shouted loudly. Angry at them for not backing away.
Meanwhile, Ramon stayed where he was, his eyes fixed on his wife, so did Hailee.
The cops who were there didn't lower their guns, but they didn't get in the way of the two men as the two of them moved more and more toward the way they were going either.
The tension was palpable in the air right now and one wrong move, one unexpected shot, would take a real life.
Ramon wasn't going to gamble with the possibility of his wife getting hurt, but he wasn't going to let the two of them take Hailee away either.
He knew that Hailee would become a very valuable chess piece for Leon in the future, because they both knew Ramon would do anything to get his wife back.
