A Better Way to Control Firearms

It's simple - record each weapon and ammunition sale. Who sold it and who bought it - then put this in a Federal database. Anyone who accumulates too much of either one would be investigated. This would not stop shootings where only a few people are involved - but mass shootings would be eliminated.

A similar strategy could be used to determine what money is where. If banks were required to record the deposits and withdrawals to every bank account. Paper money going either way would be scanned to determine its value. This could be improved by recording the serial number of every bill.

The tricky part would be determining who owns all these bank accounts. But this could probably be determined - once the pattern of all the bank transactions are known - and especially when transfers, to and from, foreign banks are made.
