Prophet Mohammad said, "Kill any Muslim leaving Islam." (Sahih Bukhari , 4:52:260)
The Reliance of Traveller, manual of Islamic jurisprudence in Shafi'i school of Islamic thought, approved and certified by Al-Azhar University in Cairo to be authentic and a reliable guide for Muslims living in the West, says - in the section 'o' and chapter 8 (here):
"Leaving Islam is the ugliest form of unbelief (kufr) and the worst.
When a person who has reached puberty and is sane voluntarily apostatizes from Islam, he deserves to be killed."
So, it looks like Al-Azhar University, the seat of highest authority in Sunni school of Islam, is confused on 'No Compulsion in Islam.'
Traditionally, in Classical Islam, for 1400 years, it was never understood like what Muslim spin doctors suggest to keep infidels under false sense of security. Lying is never a problem for many Muslim spokesmen and so called Muslim reformers. Finally, it all amounts to how we understand 'Compulsion' !

Other important point to be noted from this incident is, while Sharia law may be a constitution of Islamic state but IT IS ALSO PART OF BELIEFS OF MUSLIMS implying Muslims can always act upon it because they equally know that Sharia law does not punish those who kill apostates. And you always see individual Muslims or groups acting on it and enforcing it. Undeniably, Non-Muslims and Women become first and second victims of provisions of Sharia.
