When Seth is spitting out the jelly beans just before he and Derek are about to leave the Vinyard home, you can see assorted colors shoot out of Seths mouth. Although, just a second before, the bowl was filled with all white jelly beans and one black ones until Seth picks out the black one and tosses it.
When the family is fighting around the dinner table and it gets so bad that everybody is standing and yelling at each other, Derek's mom pulls on his shirt, opening up several snaps or buttons. When the scene is ending, Derek opens up his shirt by pulling it open quickly, but all of the buttons or snaps are closed again for this effect.
The first time when Derek was stacking the sheets, he threw a stack of sheets onto the shelf behind him, where they lay all disorganized. In the next few seconds, the sheets that had been thrown keep changing positions, and the piles of sheets on the table change positions between shots.
As Derek and Danny are leaving the coffee shop, Daniel's hands are empty when he tells Sweeney he'll have the paper ready, however a moment later, Danny has a bag and a drink in his hands.
When the police officer is pulling Derek off the ground after the shooting, he has his right arm over Derek's chest. In the next shot, he has his left arm, and then in the next shot his right arm again. (This is the second flashback to this incident, occurring about 1 hour into the film.)
In the opening scene, Derek fires 24 shots without reloading from a Ruger P94, which could hold no more than 10 rounds in the magazine and one in the chamber.
One of the first two inmates to exit the shower before Derek is attacked has a nipple ring. Inmates would not be allowed to wear jewelry of any kind.
During the riot at the mini-mart, someone throws a cash-register through an office window. In the shot before the throw, the glass is reinforced. When the register goes through the window, it is not.
(added) The glass merely appears to be reinforced. The matrix appearance on the glass is actually from the pegboard on the wall inside the room. It is not reinforced glass.

Derek Vinyard would have been found guilty of the supermarket robbery once his fingerprints were in the system for the murder. Derek wore no gloves when he threw the register through the window. He clearly gave them a good palm print with fingertips.
(added) This may be true, perhaps in a TV crime/drama series. While it is possible latent hand and finger prints may be lifted from the cash register, it is not guaranteed. That is to say the texture of the register may not allow usable latent prints, or a lifted print would be of high enough quality for an electronic comparison. Most latent finger and hand prints are not conclusive, in any case.

When we see a close-up of Danny's hands while he is typing his final draft, he never hits the space bar.
In the beginning of the film, when Derek runs out of the house and finishes shooting at the thief stealing his truck, in slow motion he turns around facing the camera, with the gun still in the same hand he was using to fire it. Later on in the movie, when this scene is replayed from a different shot, he turns around and puts the gun in his other hand.
In the black vs. white basketball game, Derek makes a shot and then Seth says, "Should've passed it to me I was wide open." His mouth doesn't match these words.
When Danny is printing his essay, the ink-jet printer makes a dot-matrix sound.
When the two brothers are sitting in the bedroom and Danny gets up off the bed, you hear him talking to Derek but his mouth is not moving.
When Derek tells Cameron he and his brother are out, the reflection of the cameraman is clearly visible.
While the group is walking to the supermarket after Derek's speech, you can see a shadow of the Steadicam on the road.
Camera operator reflected in the coffeehouse window.
When Derek and Cameron are talking in front of the portrait of Adolf Hitler, you can see reflection of cameraman on the portrait.
When Derek runs through the school hallway towards the end he passed a crowd of kids. A boom mic and camera operator can be seen standing in the crowd.
In the flashback to Dennis Vinyard's death, it is stated that he was an LA County Firefighter. In the flashback scene with Danny at the breakfast table, Dennis Vinyard has an eagle on the badge. The Los Angeles County Fire Department has a bear on the badge. The Los Angeles (city) Fire Department has an eagle.
The coffee shop Derek and Danny walk to at the end is on the corner of Fairfax and Wilshire, or about a four hour walk from Venice where they live.
When Dr. Sweeney is telling Danny to do a report on Derek, the reflection of the boom mic is clearly visible in the glass window of a cabinet behind Sweeney's head.
When Derek is confronting Cameron in his office at the party, the shadow of the boom mic is clearly visible on the wall and on the floor on the right side of the screen, following the actors as they talk.
The gang member rapes Derek in the shower without using lubricant. A person needs lubricant for anal sex (or rape).
