I think that Mr. Ollivander might be unwilling to sell a wand to Filch
if he dared to walk into that shop (Mr. O. has an uncanny ability to
size up his customers and would probably know a Squib when he saw
one). Granted, he sold a wand to "little" Hagrid, but Hagrid must have
come to the shop accompanied by his wizard father and must have been
listed in the book that records the birth of magical children or he
wouldn't have received a letter from Hogwarts. Filch probably didn't
have any such letter, and Mr. O. would know it. However, if he
couldn't buy a wand from Ollivander, he could easily buy one from a
used wand shop in Knockturn Alley, whose owners wouldn't have any such
scruples.

Carol, who thinks that Squibs have some latent magic in them because
they can see things that Muggles can't
