Well, the way I read it, it is an average of 27/28 days per child, out of about 7 months of school... so, 25 weeks of school (after subtracting for Xmas and Thanksgiving)? That is about 1 day per week.
That is too much. But, I have had my kids in schools that the clocks are different in every classroom and different from the front office. (No centralized bell system---it was private school). I never knew for SURE what time they got to school (the office clock would be different from day to day). One kid would be late, one would have spare time---and they went in at the same time. But, I didn't know one kid was late until the progress reports came out...no one said, "Hey, your daughter is late to school" and I was at the school a lot as a volunteer. And it was the same thing at the end of the day: they were supposed to get out at "x" time, but they never came out then... there was a delay... some days it was 2 minutes, some days it was 10 minutes... with no explanation. Maybe the kids took too long for their last trip to the bathroom as they were lined up to exit the building... ? Or maybe the class rooms weren't operating on the same time.
Drove me crazy really.
My husband operates on GMT at work, and his watch and car are set to the exact time based on his work. My watch says something different. It matches what I hear on the radio every day. My car too. The school (office) had a totally different time than either of us. And sometimes that would change (either earlier or later)... with no warning.
Now, I don't know what the situation is where the kids in the article were in school---in Washington and he's a lawyer, so I suppose it could be a private school? Did they notify the parents that the kids weren't making it on time? Does their contract with the school specify the penalty for tardiness? If the answers are yes to both, then as long as they are following the terms of the contract, fine away.
And yes, I get that it can be disruptive to the teacher and class... though I have never been in a single class (except in college) that the teacher was actually starting anything the moment the bell rang. But charging the parents with a misdemeanor, did I read that in the article? As what? Child neglect? I can think of a LOT worse ways of neglect. I'm betting those kids ate a healthy breakfast at home, had clean and weather appropriate clothes on, and had their homework done and with them.
I just don't think there was enough information in the article to be fair to both sides, particularly in light of how they try to make the tardies appear even worse than they are by making it sound like all the kids were late 85 times EACH, which is not the case.
ETA: Just wanted to add a note, after reading the other responses so far--
I find it interesting how many ladies have zero tolerance and no compassion whatsoever on any level about how rude this is to the rest of the class or the teacher and assert what horrible things this is teaching their children about respecting others. (even though, we are not talking about them coming in 15 or even 10 minutes late.... they said it was 2-3 minutes late most of those times--so no way their teachers are having to reteach any lessons, I can guarantee)--- in comparison to how many people (not just on the most recent thread, but others I've seen on this board in the past) think it is just fine and have no issue with not getting around to responding to an RSVP, because "it happens sometimes, people get busy" or "cut the mom some slack she knows she should have responded", etc. Very interesting.
