Kinnear blasts keeper
The Hatters were 1-0 up when two goals in the space of four minutes in the second half gave The Spireites all three points at Saltergate.
Kinnear was left fuming after Emberson and centre half Ian Hillier allowed David Reeves to nip in and score Chesterfield's winner just before the hour mark.
The former Wimbledon boss felt Emberson had bungled Chesterfield's second goal into his own net and went on to suggest that his number one has `thrown in` at least a goal a game this season.
Kinnear said: "We need to score twice every time we play because the keeper is always going to throw one in.
"The second goal was an own goal by him.
"They've given it to David Reeves on the video but it's clearly an own goal.
"He's punched it into the net.
"He threw one in last week at Wycombe.
"It's another goalkeeping error and I could write a book on them.
"Goals like that drive you insane."
Kinnear may now turn to his other goalkeeping options in Mark Ovendale and Dean Brill when Luton host Plymouth Argyle in Division Two on January 11.
