Table schema:
CREATE TABLE TV_Channel (country VARCHAR, id VARCHAR); CREATE TABLE TV_Channel (country VARCHAR); CREATE TABLE cartoon (Channel VARCHAR, written_by VARCHAR)

Question: which countries' tv channels are not playing any cartoon written by Todd Casey?
SQL: SELECT country FROM TV_Channel EXCEPT SELECT T1.country FROM TV_Channel AS T1 JOIN cartoon AS T2 ON T1.id = T2.Channel WHERE T2.written_by = 'Todd Casey'
