On: Call of Duty gaming community points to ‘swatting’...

The person you replied to did not explain why not to rent concrete slabs, and so did not raise the point you're pretending it raised.

In general, it's unwise to agree with those who shroud their violence-fantasies in truisms. Also, since english is not that person's first language.

I didn't explicitly say why renting concrete slabs is a bad thing because I think most HNers can understand without needing additional explanation
