As a suggestion, list the columns on your insert. That way it's much
easier to figure out what data goes with what column:

Looking at the columns below and the data above it looks like you put
the 1 in the wrong place.  The last 3 columns should be permit_printed,
firearms_licence, drivers_license, where above you're using
firearms_licence, drivers_license, permit_printed.  The ordering
is the table's ordering unless you specify column names.
