The Clarets went into their clash with Bristol City looking to extend their perfect record at Turf Moor, but had to settle for a goalless draw.
Laws was disappointed not to pick up three points, especially after Burnley had been awarded a first-half penalty.
Alexander sent his effort wide, failing to score a penalty for the first time in a Clarets shirt.
"You could see the silence and the shock that we hadn't won the game," said Laws.
"We've had something like 25 shots on goal and the goalpost and bar have been very supportive (for City).
"We know we've dropped two points, but you've got to give credit to the opposition because they've obviously seen us in midweek and come here with a game plan.
"I think we were all shocked when Graham Alexander's penalty went wide. It becomes a formality. He has a phenomenal record and it was probably inevitable he'd miss one eventually.
"He's disappointed because he believes they are a formality, but I certainly won't be giving him a hard time. He'll be working hard and he'll be first in line the next time we get a penalty."
