There is no proof that the Tempus is not guilty of the dubious end of day trades. Just because it may be illegal for individuals directly linked to the company to trade TMPS on the open market does not mean that they can't find ways to make those little trades happen.
If the volume of the trades were much higher, then yes it would be easier to get caught, but if the CEO's cousin or next door neighbor decides to buy 500 shares at a price 2 cents above the market price to close out the day, there is no law against it unless there is proof that the neighbor was told specifically by the CEO.
Even then, it would be close to impossible to obtain such proof that would be admissible in court unless the guilty party cooperated with law enforcement.
The key question is this: When EOD trades are used to paint up the TMPS share price, who stands to gain the most? And the answer is, the company. Once again, not enough proof to throw TMPS employees or execs in jail, but enough circumstantial evidence to come to the conclusion that buying this stock is a bad idea.
