Thank God for shielding bookcases. I wonder if a recently purchased house is covered by some kind of guarantee/warranty through the realtors or insurance company, because someone should have been in charge of the maintenance/inspection of the house before it was sold. Someone probably ould have been held criminally liable if you had been hurt :(

Don't forget to check the electrical outlets (this or next house) as well since sometimes they aren't grounded or shorting out >_>;
