At the end of the day, actions have consequences, and criminal or institutional records affect your application, as they reflect upon your character. If people do not want to face those consequences or have their character called into question, they should not engage in those activities. This is, to me, a relatively small ding on someone's character and judgment, but it's there nonetheless.
Own your actions and move on, that's all you can do. Nothing, to me, it's more annoying than the "everybody is doing it" excuse, as that says "I do not take any responsibility for this." "I made a stupid mistake and I got caught, but that isn't who I am" is the proper approach, as demonstrated by some good letters and ECs.
