For those with kids on high school, the following is a description of an event that happened last Sunday around the corner from us. I have deleted details, although I don't think it's terribly private as this was posted on a relatively public forum already:
On Sunday night, 80~100 teenagers showed up uninvited at our house after someone deliberately placed a fictitious ad via social medial identifying our house as a high school party location. My daughter was home with 2 other girls at the time and a group of 9 unknown teens climbed over our locked side gate and barged through our unlocked door to the kitchen. While she was confronting them and trying to get them out, more high schoolers started to show up from other entrances. As my daughter/friends went to guard the front gate, and made their best effort to turn people away, more got in by climbing over our side gate and backyard. Many brought in alcohol, and ransacked our house while my daughter and her friends were completely helpless and defenseless. The crowds were finally disbursed when police showed up around 11pm. Fortunately no one was injured but my house was badly vandalized, furniture damaged and items/jewelery were stolen. I apologize for the disturbance this has caused our neighbors on the street and bless the hearts to those kids who stayed hours after to help with cleanup. This apparently happened to several other neighbors before, but I hope won't happen to anyone else!
Most alarm systems have a panic button but we neglected, up until now, to teach our kids to use it. To me, it seems as though the people who came barging in were the ones who placed the fictitious party ad. I haven't found out yet whether these kids were known to the girls who were home - I assume at least tangentially. Really hard to believe.
