This was posted on the Park Slope Forum last night. Let’s just say our reaction is highly negative:

In an attempt to prevent dogs from walking in front of his house, an occupant on the south side of 11th Street between 3rd and 4th Avenue has crushed and liberally sprinkled moth balls all over the sidewalk in front of his house. The ingestion of moth balls can cause vomiting, seizures and liver failure. The police refuse to take action, saying it’s “not illegal.” Please exercise caution when walking your pooch on this block.

Wow. What a sick, mean thing to do.
