And this database was recently used to apprehend a South London gang member who used his dog to catch a 16-year-old rival and hold him while he stabbed him to death.

The creation of human DNA databases has led to widespread debates on privacy; but what about the collation of DNA from dogs or other animals?"
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
