The legion of death

The riddle

James Gordon's POV

I examined the body's at the gates of Arkham.
They were both guards one of them had there neck snapped and the other was shot. I looked at the way the guards neck was snapped it had to be someone strong. I looked at the other one when he was shot it had to kill him right away. it had to be a powerful gun to have killed him right away.

Where is the other guards gun. I asked one of the officers.

It's in this bag right here. He handed me a bag.

.i got a glove and got it out. I got all the Bullets out of it. There was one missing. I put the gun back in the bag.

I gave it back to the officer.

Where did you find the gun. I asked.

It was right next to him. He said.

I looked at the body again and I saw something on his face it looked like water but then i noticed it was brown.

I need to look at the security cameras. I said.

One of the officers showed me the cameras outside the footage showed a black van pull up to the gates one of the guards went up to the window the window rolled down and then the guard looked like he was trying to wipe something of his face then he looked at the other guard and screamed he then pulled out his house and fired at the guard. Then someone can out of the van and snapped his neck. I looked at that part again and saw the figure and immediately recognized the figure as bane.
Then I looked at the other part of the footage with the van I got a good look at the face. In the van. It was scarecrow.

I then looked at the footage of the entrance to Arkham bane got out of the van again and busted open the doors the three guards there not knowing what was happening were all hit with a blast.

I saw where the blast came from it was mr freeze.

I then looked at the footage of them going to the 3rd floor and then when they got up there 5 guards came towards them with stuff in there hands they then followed them to the second hallway.

When they got there. One of the guards opened 3 cells the riddler. Penguin . And the mad hatter each stepped out. The guard then told scarecrow something I don't know what but scarecrow moved to the side of the wall and bane and mr freeze killed all of them. Then ten guards came at the entrance of the hallway and screamed freeze! Then mr freeze blasted them with his gun.

Then as they made there way towards the stars
But before they did the mad hatter stopped and walked over to a guard that was lying on the ground. Freeze must have missed him when he fired his gun. But then the mad hatter slit his neck. Then they left.

I then switched it to the gates of Arkham again. before leaving I saw the riddler put a piece of paper in one of the guards pockets.

I ran back outside and looked in the guards pockets and I soon found the note it said

What cOmes once in a mInuTe twiCe in a momEnT but never in a thousand YeaRs?

Why is some of the letters capitalized. I thought. I need to give it to Batman.
