I was tuned in to the www in 1998. Lot’s of mischief to be had then... 1995? not so sure that it would have been devoid of all things illegal.
Even so, there were irregularities in the damage done to the building which suggest that other explosives may have been involved.
Beiruit, and the Khobar towers, iirc, used the same explosive and a similar M.O.
