Police Involvement - Reception Drinking

While my husband and I are visiting his parents before we head over to NYC, we've been talking with them about everything that happened at the wedding and reception. They were somewhat mortified at the amount of drinking that went on at the wedding. I was not - my family is Irish Catholic, my friends know how to drink, and so do my husband's.

The worst that happened is that my brother and brother-in-law were doing shots, so they were, as we say in the biz, hammered. They both had rides home, though my brother had the keys to my parents' car in his hand when he went outside so was stopped by the security guards/police officers. I think my husband's parents were more embarrassed by the fact that the best man fell down the grand, curvy staircase (only about half of it - and after we left). In my eyes, this is tame.

Let us review the facts from my sister's wedding that led to the police being involved three times:
1) After the rehearsal dinner, everyone was at the hotel hanging out at the pool having some beverages. This apparently intimidated the desk staff, so at 10:00 they called the police to come and tell us that the pool area was closed.
2) Also the night before the wedding, one of my second cousins had been drinking and then went to the casino down the block (wedding was in St. Charles, MO). One of the police officers at the casino decided he was too intoxicated to make responsible gambling choices (MO watches out for you when you gamble and will cut you off). J mouthed off to the policeman and was escorted downtown to be bailed out by my dad and his uncle.
3) One of my brother-in-law's relative's car was stolen out of the hotel parking lot (including the two car seats for his kids). (Not really scandalous police involvement, but a black-and-white appearance nonetheless)
