Hello, i am student. have an assignment about cross examination by defendant attorney

i have declaration of witness i need to know questions .

My name is Mr. Z. I'm the manager of Player's Video Arcade. At about 8:15 p.m. on November 04, 2021, I was seated at the front counter when I saw D.X and T.D walk from the main game area to the fountain, where D.X began washing his hand. D got mad and said, "Just leave me alone," or "Just let it alone." A few moments later, P walked towards the front counter. Mr. .P then pulled his wallet from his back pocket. I noticed this because people often come to the desk and ask me to change a bill. As P walked past the counter, I resumed glancing through a brochure for a new video game called "Briefcase Warriors." I looked up in time to see Mr. D hit Mr. P across the face with a piece of wood that usually sits on the windowsill. The wood is used to prop the window open on hot days. P groaned and fell to the floor. He wasn't moving. When P was hit, C. C was a few feet behind him. For a few seconds, she just stood there; Mr. D stood with the stick in his hands --- nobody moved. It all happened so fast that at first it was as if they were in suspended animation. Then Mrs. C ran to Mr. P side. Mr. D dropped the piece of wood and ran out the door. I ran from behind the counter after Mr. D ran alongside the building towards the rear, but seemed unsure of where he should go. His hesitation allowed me to catch up with him. I grabbed him by the arm and said, "Why did you do that? Why'd you hit him like that?" Mr. D replied, "I had to man, I just had to." I remember this clearly, I took Mr. D back to the arcade where I called the police. This is the first time there has been trouble since I've been the arcade manager
