Warrington and Apparating

[l.anne120]

No: HPFGUIDX 181712

I Have a question that may have been answered, but I haven't been reading the posts on this 
group for very long.  I'm just re-reading OotP and I'm still wondering if JKR made a mistake 
here.   Fred and George were responsible for putting the Slytherin Quidich captain Warrington 
into the vanishing cabinet, the one that Draco fixes in HBP which ultimately allows the Death 
Easters into Hogwarts.  Draco says to Dumbledore that Warrington apparated OUT of the 
cabinet - we witness this through Harry's eyes when Draco interrupts a Occulemeny lesson to 
tell Snape that they found Warrington in a toilet.  

My question: as Hermoine ceaselessly reminds us, "you can't apparate into or out of 
Hogwarts."  But Draco clearly states that Warrington "nearly died" by apparating out of the 
cabinet and into Hogwarts.  This seems like a clear violation of the magical rules established 
by JKR.  So what gives?  Did Warrington apparate into Hogwarts or is there some other 
explanation that isn't clear to me after several readings of the series?  If JKR has explained 
this, I'd love to see the reference.  If this subject has been thoroughly canvassed, please refer 
me to the appropriate thread and I'd be glad to read up on this.

Thanks
