Doakes and L were in the same position. They were operating purely on hunches, and had no real proof to substantiate their hunch. And as such, the people around them would view their accusations as bullying or misplaced vendettas.
L knew it was Light, but he wanted to be wrong. Therefore, he would accept any new evidence that proved him wrong. That's the difference between L and Doakes.
L liked Light and hoped he wasn't guilty.
Doakes hated Dexter and wanted him to be guilty.
