What are the behaviors of capacitors and inductors at time t=0?

For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.
