Caught in a lie

We've been a having a little honesty problem around our house lately.  Nothing big.  Just little white lies.
"Go brush your teeth."
"I did."
I feel the toothbrush, and it's completely dry.  No teeth have been brushed.
Well, the other day, we have actual video/camera evidence of a lie. It was a little embarrassing for the kids.
I was out running/going to the grocery store early on a Saturday morning.  Dad slept in a little, which means the kids were left to their own devices. When I came home, the 7 and 5 year old promptly tell me that the 4 year old has been eating candy.
"She stole some candy!"
"What?"
"She stole some candy and was eating it downstairs!"
"What candy?"
"Dad's candy bars. [For his lunches]. She had a Crunch bar. And a 100 Grand."
"Where are the wrappers?"
"They're downstairs."
Meanwhile, the 4 year old is protesting, "I did not! They ate some too!"
While the 5 and 7 year old are strongly denying eating any.
It sounds so neat when you write it down like that, but really, it involves 3 children yelling, accusing, and denying simultaneously.  I wish I could have taped the chaos to truly describe it. They bring up wrappers for 2 Crunch bars, a half eaten Crunch bar, a partially eaten 100 Grand, an open bag of peanut M&Ms and a bag of chocolate covered caramels. Needless to say, the treats have now been hidden and the 4 year old doesn't get any treats for the rest of the week.

Later that day, we found the camera hidden under the bed in our room.  The 7 year old just recently learned that she can take pictures and video by herself. Here's what we found in reviewing the tape:

By the way, this is the 5 year old, not the 4 year old.  One who vehemently denied eating any of the candy and blamed it on his 4 year old sister.  Obviously, the thought that Mom and Dad may actually look at the pictures never entered his mind.  It's actually a great shot taken by the 7 year old.

And there's more. Like I said, the 7 year old also learned how to take videos on the camera. Kind of.

Needless to say, I don't think there will be so much playing with the camera.  Certainly not when kids are doing something they shouldn't. As for the lying, I'm not sure this will stop that.
